Interface Materials CMP-4000

CMP-4000 Gasket Material

CMP-4000 gasket material is a high performance, compressed MicroPore material that combines a unique synthetic fiber matrix with a fully cured nitrile butadiene rubber binder. Hydro-Fused® CMP-4000 gaskets have excellent sealability and torque retention properties and are recommended for short duration maximum temperatures up to 350°C (650°F).

Typical OEM and Industrial applications for CMP-4000 gaskets include engine, transmission, hydraulics, pumps, valves, pipes, and compressors that operate from -40°C to 150°C and from 0 to 40 Bar internal pressure. Applications outside this temperature and pressure range can be considered with proper validation testing.

CMP-4000 Gasket Material for OEM and Industrial Applications

Accurate Felt & Gasket has been in business since 1951 and is ISO 9001: 2015 registered. We offer CMP-4000 gasket material and manufacture custom CMP-4000 gaskets for a range of original equipment (OE) and industrial maintenance, repair and operation (MRO) applications.

Utility-grade CMP-4000 gasket material has a distinctive, green color that makes it easy to identify and meets classification ASTM F-104: F722930E22M9 for commercial nonmetallic gasket materials.  

If green CMP-4000 material isn’t the right option for your application, we also offer a wide variety of other Interface Performance Materials in full rolls, sheets or even a few yards designed to fit all your requirements. CMP-4000 gasket material is also available laminated with a variety of adhesives.

For questions regarding custom die cut CMP-4000 gaskets or any of our in-house secondary services, please contact our gasket experts.
