Style Hi-Tex 337
Metal Reinforced Fiber Gasket Material
Product Line Sheet


Construction/ Description

Hi-Tex 337 is completely Non-Asbestos. Hi-Tex 337 uses a .008” EPT (Electrolytic Tin Plate) steel core. The core is then laminated with facing compressed of 75% pure graphite and Kevlar fiber reinforcements. The modified nitrile binder system makes it a very durable and universal graphite material. The finished gasket edges are smooth and will resist chipping and flaking.

Application / Service

Hi-Tex 337 is an excellent material that will perform very well in high heat, chemical, and pressure applications. This material is commonly applied to cylinder head gaskets, intake manifold gaskets, exhaust manifold gaskets, carburetor and turbo charger gaskets, ERG gaskets, high pressure/ temperature stationary engine parts, compressor gaskets, and small engine gaskets.
