S-309 Cellulose Gasket Material: 7 Selection Rules for Oil, Fuel & Water Areas

September 16, 2026

S-309 Cellulose Gasket Material is a non-asbestos soft gasket material listed by Charminar Jointings. The product page describes it as a cellulose fibre gasket material with SBR binder, suitable as a replacement for asbestos fibre gasket materials and saturated paper. It is mentioned for many oil and coolant applications, including oil, fuel and water areas.This blog explains how buyers, maintenance teams and specification teams can evaluate S-309 Cellulose Gasket Material for practical applications. S-309 Cellulose Gasket Material is treated here as a specific Charminar product, not a broad gasket category. The content is limited to the product details available on the Charminar website, including its composition, listed applications, fluid resistance table, temperature value, roll availability and request-based antistick coating option.

What S-309 Cellulose Gasket Material Is

S-309 Cellulose Gasket Material belongs to the non-asbestos soft gasket material range on the Charminar website. The product page describes it as cellulose fibre gasket material with SBR binder. It is also described as an economical alternative for soft gasket applications such as oil, fuel and water areas, carburetors, gearboxes, oil pans, material handling equipment, chemical pumps, pipe lines and diesel engines.

This makes S-309 Cellulose Gasket Material a suitable topic for a product-specific blog because the application language is already present on the website. S-309 Cellulose Gasket Material should be evaluated through this listed application language. Instead of making broad industry claims, the blog should explain how buyers can read the available product data and connect it with their actual application.

Rule 1: Match S-309 Cellulose Gasket Material with Oil, Fuel and Water Areas

The first selection rule is to match S-309 Cellulose Gasket Material with the application areas mentioned on the product page. S-309 Cellulose Gasket Material should be checked against the actual service area before approval. The website specifically mentions oil and coolant applications and also lists oil, fuel and water areas. These terms should guide the content and the buyer discussion.

For a maintenance team, this means the product should be considered when the job is close to the listed soft gasket applications. It should not be promoted for unrelated media or unlisted extreme conditions. The safe approach is to compare the job requirement with the listed applications and then confirm with Charminar if the condition is not straightforward.

Non-asbestos soft gasket material for oil fuel water

A non-asbestos soft gasket material for oil fuel water service should be reviewed by actual use area, product grade and technical data. S-309 Cellulose Gasket Material gives buyers a website-listed option for these application areas.

Rule 2: Check the Cellulose Fibre and SBR Binder Composition

The S-309 product page gives the composition clearly: cellulose fibre gasket material with SBR binder. This information is important because product selection should not be reduced to sheet colour or general gasket size. Composition helps a buyer understand which grade is being discussed and prevents confusion with another material in the beater addition and cellulose fibre category.

S-309 Cellulose Gasket Material is also described on the website as a suitable replacement for asbestos fibre gasket materials and saturated paper. This line should be used carefully and exactly. The blog should not add extra safety claims or regulatory statements. It should simply present the website-supported description and connect it with practical product selection.

Cellulose fibre gasket sheet with SBR binder

Cellulose fibre gasket sheet with SBR binder is the main composition note for S-309 Cellulose Gasket Material. Specification teams can use this phrase while preparing enquiries or comparing product pages.

Rule 3: Review Fluid Resistance Data for S-309 Cellulose Gasket Material

The product page provides fluid resistance values under ASTM F-146 for ASTM Oil No. 3, ASTM Fuel B and distilled water. For ASTM Oil No. 3, the listed thickness increase is 10% maximum and weight increase is 45% maximum. For ASTM Fuel B, the listed thickness increase is 10% maximum and weight increase is 45% maximum. For distilled water, the listed thickness increase is 30% maximum and weight increase is 60% maximum.

These values help buyers review S-309 Cellulose Gasket Material in a structured way. Fluid resistance data should be compared with the actual media and working conditions. The data is a technical reference, not a substitute for application review. For general understanding of how gaskets work in joints, readers may refer to the Wikipedia page on

gaskets, while the product decision should remain based on Charminar’s data.

Fluid resistance gasket material for oil and fuel

Fluid resistance gasket material for oil and fuel applications should be checked through the product’s own technical table. S-309 Cellulose Gasket Material includes listed values for oil, fuel and distilled water exposure.

Rule 4: Confirm the Temperature Suitability of S-309 Cellulose Gasket Material

The S-309 product page mentions maximum operating temperature up to 150 degrees Celsius. This value is important for selection because temperature can affect gasket performance. Buyers should compare the actual working temperature with the value mentioned on the product page before approving S-309 Cellulose Gasket Material.The product should not be positioned for higher temperature service unless Charminar confirms it for a specific application. For applications outside the listed condition, buyers should check other Charminar product pages or speak with the company. This keeps the content accurate and avoids unsupported claims.

Soft gasket material temperature check

A soft gasket material temperature check is a simple but necessary step. For S-309 Cellulose Gasket Material, the website-supported maximum operating temperature is up to 150 degrees Celsius.

Rule 5: Match Listed Applications with Real Maintenance Requirements

The S-309 page lists several application examples: oil and coolant applications, oil/fuel/water areas, carburetors, gearboxes, oil pans, material handling equipment, chemical pumps and pipe lines, and diesel engines. These are useful application references for the blog, because they are directly available on the product page.

For diesel engine related application context, readers can refer to general background on the Wikipedia page for

diesel engines. However, the blog should not suggest specific engine models, machine brands or unlisted technical performance. S-309 Cellulose Gasket Material should be discussed according to Charminar’s stated application list and specifications.

Gasket material for gearboxes oil pans and chemical pumps

Gasket material for gearboxes oil pans and chemical pumps should be selected with the actual site condition in mind. S-309 Cellulose Gasket Material can be considered where the application is aligned with the product page and the temperature and fluid data are suitable.

Rule 6: Review Roll Width, Roll Weight and Thickness Range

Availability is also part of buying. The S-309 product page lists roll width as 1200 mm, roll weight as 50 to 250 kg, thickness range as 0.30 mm to 1.50 mm and core size as 75 mm. These details help procurement teams prepare a proper enquiry instead of sending an incomplete requirement. For S-309 Cellulose Gasket Material, thickness should be matched with the actual gasket design, joint requirement and application. S-309 Cellulose Gasket Material should not be assigned a universal thickness without reviewing the actual requirement. The blog should not recommend one universal thickness. It should guide the buyer to check the available thickness range and then contact Charminar for the exact requirement.

Cellulose gasket material roll size and thickness

Cellulose gasket material roll size and thickness information helps buyers plan inventory, conversion and enquiry details. S-309 Cellulose Gasket Material provides these availability details on its product page.

Rule 7: Ask for Support Before Final Purchase

The final rule is to ask for support when the application details are not fully clear. S-309 Cellulose Gasket Material should be discussed with the supplier when the service detail is not fully defined. The product page includes a contact option and enquiry route. Buyers should share details such as application area, media, working temperature, required thickness, quantity and any handling preference.

For more product details, users can review the S-309 product page and the Beater Addition Jointing & Cellulose Fibre Gasket Material category. These pages keep the buyer journey connected to Charminar’s actual product range.

Final Buyer Checklist for S-309 Cellulose Gasket Material

Before selecting S-309 Cellulose Gasket Material, check whether the application is oil, fuel, water, coolant or one of the listed soft gasket areas. Review the cellulose fibre and SBR binder composition. Check the fluid resistance values for oil, fuel and distilled water. Compare the operating temperature with the website value of up to 150 degrees Celsius. Review roll width, roll weight, thickness range and core size. Contact Charminar if the requirement needs confirmation. A focused selection process helps prevent confusion between different gasket materials. S-309 Cellulose Gasket Material should be presented as a defined Charminar product with specific website-listed applications and specifications. S-309 Cellulose Gasket Material should be selected with the product page as the main reference. That is the safest way to create useful content for buyers while keeping the blog accurate, product-specific and SEO-friendly.
