Frequently Asked Questions About Gasket Material

Most standard repairs have thicknesses between 1/32 and 1/8 in. If a surface shows visible warping or uneven wear, go with a thicker sheet.
Rubber handles moisture and pressure cycling well, while cork is better suited to oil-contact applications such as engine covers and valve housings. Both come in roll form, so you can cut exactly what you need.
Once a gasket has been compressed and removed, it won't fit a second time. Cut a fresh piece from the roll for each repair.

Gasket Material

A leaking joint in a pipe, engine or appliance usually comes down to a failed gasket. Cutting your own replacement from our gasket material lets you match the shape and thickness exactly. Tractor Supply carries gasket material, along with our supporting adhesives and sealants, to cover repairs across plumbing, automotive and general maintenance.

Built to Block Leaks at the Source

Any time two surfaces meet under pressure, a gasket is what keeps fluid or gas from pushing through the gap. Sheet gasket material lets you cut a custom replacement on the spot rather than tracking down a specific part. Sealed with a gasket maker formula, it compresses between the two sides of a joint to fill gaps that would allow fluid or gas to escape. The right type depends on your system's operating temperature, fluid type and pressure.

Rubber and cork are the two most common formats, and each handles a different range of conditions:

Rubber Rolls for Plumbing and Pump Repairs

Water lines, pump housings and chemical connections put constant stress on a joint. Rubber handles that load well, compressing under pressure and returning to shape after, without cracking or taking on moisture over time. A rubber gasket stays sealed through temperature swings that would cause a less flexible material to harden. Cutting it down with standard hardware tools is straightforward, so fitting a replacement doesn't require much beyond a utility knife and a flat surface.

Cork Rolls for Engine and Oil-Contact Repairs

Oil pans, valve covers and engine gasket surfaces are rarely perfectly flat, and cork accounts for that. It compresses evenly and fits against minor surface imperfections that a stiffer material would bridge rather than fill. Cork holds up against oil and petroleum-based fluids, which makes it a practical fit for truck and automotive work and small-engine repairs. It also cuts cleanly and doesn't shift during installation, so lining up bolt holes for a proper fit stays manageable.

Find the Right Gasket Material at Tractor Supply

A roll of sheet gasket material stores easily and covers water line repairs, engine covers, pump seals and more. For Life Out Here, that kind of prep pays off when something fails mid-project. Stop in at your local Tractor Supply store or shop for gasket material and other  home improvement tools on our website.
