The standard o-ring in all the NOSHOK valves is FKM and the standard handles are “T” handles (HL2).

The handle material will always match the material of the valve, unless otherwise specified. For example, the “T” handle (HL2) on the 404-FFC will be steel. When only the standard configuration is needed, no additional designations are necessary. Please consult the factory for special
application requests.
