Product Features
- Anodized piston head increases strength and heat dissapation.
- MOST Namura pistons feature a machined head which helps reduce carbon build-up and reflect heat.
- All components are manufactured to OE-specs.
- Paper gaskets are composed of non-asbestos Nitrile Butadiene bonded cellulose fiber materials, which maintain their tensile strength and torque retention in operating conditions over 300F.
- Seals and O-rings are made of either NBR, Fluoroviton, or Silicone. Each material is selected based on the following chacteristics: Temperature resistance, abrasion resistance, chemical resistance, and their Aniline Point. In certain applications a Teflon coating is also applied to prolong service life.
