Rubber Gasket Sheet & Roll Stock

Die-cut-ready sheet and roll stock in NBR, EPDM, neoprene, silicone and PTFE. Standard thicknesses for MRO and fabrication shops.

Overview

Rubber gasket sheet and roll stock give maintenance teams and fabrication shops the flexibility to cut seals on demand without waiting for custom tooling. We supply sheet gasket material in the same elastomer families used for our finished gaskets: NBR for oil resistance, EPDM for water and weather, neoprene for outdoor and refrigeration, silicone for food and high temperature, and PTFE for chemical service. Standard sheet sizes are typically 1.0 m × 1.0 m or 1.0 m × 1.5 m, with roll widths up to 1.5 m depending on material and thickness. Thicknesses from 1/32 in (0.8 mm) to 1/4 in (6.4 mm) are stocked; non-standard thicknesses can be sourced or built up from thinner plies. The term rubber sheet gasket is often used interchangeably because the sheet itself becomes the gasket after cutting. When selecting sheet stock, match the material to the fluid and temperature first, then choose hardness and thickness. Softer sheets conform to rough surfaces but extrude more easily under pressure; harder sheets hold bolt load better but need smoother flanges. For high-volume repeat parts, die-cutting from sheet is usually more economical than waterjet or hand cutting. We also supply rubber gasket roll stock for long strip seals, door gaskets and automated cutting systems. MOQ starts at one sheet or one roll depending on material.

Frequently Asked Questions

What is rubber gasket sheet used for?

Rubber gasket sheet is uncut sealing material used to fabricate custom gaskets on site or in a shop. It is common in MRO, prototype work and low-volume production.

What thickness gasket sheet should I buy?

Match the sheet thickness to the flange gap and compression requirement. 1/16 in and 1/8 in are the most versatile for industrial flanges; thicker sheets tolerate rougher flanges but need more bolt travel.

Can I get rubber gasket roll stock?

Yes. Roll stock is available in EPDM, NBR, neoprene and silicone for long strip gaskets and automated cutting systems.

What is the difference between gasket sheet and gasket material?

The terms are often used interchangeably. Gasket sheet refers to flat uncut stock; gasket material is the broader term that includes sheet, roll and pre-cut forms.

Do you cut gaskets from customer-supplied sheet?

Typically we supply both the sheet and the cutting service to guarantee material traceability. Contact us if you need cutting-only service on your material.
