FKM (viton type) seals.
Max PSI: 225
Polypropylene is reinforced with fiberglass for additional strength.
Precision molded in polypropylene.
PTFE self-lubricating stem bushings and seats cannot stick or bind.
Self-aligning ball moves freely against the PTFE seats for smooth operation.

Advantages: Outstanding resistance to high heat; excellent resistance to oil, gasoline, hydraulic fluids and hydrocarbon solvents; good flame retardance; very good impermeability to gases and vapor; very good resistance to weather, oxygen, ozone, and sunlight.
Limitations: Poor resistance to tear and cut growth;very little resistance to oxygenated solvents; fair adhesion to fabrics and metals.
Advantages: outstanding weather resistance, high resistance to ozone, and high resistance to the degrading effects of exposure to such solvents as acetone, MEK, and xylene.
Limitations: Very poor elastic memory making it subject to tearing during installation.
