PTFE Chevron Packing used for Pump and Valve

                                   PTFE Chevron Packing

PTFE Chevron seal sets can be fitted to pistons having pressure on one side or "back-to- back" for two sides. A typical PTFE chevron packing set consists of a radial PTFE seals followed by several V-rings and a pressure ring.

Made of PTFE, these V-ring packing seals have excellent chemical resistance and withstand a wide temperature range of -110° F to 500° F. Stack as many V-rings as you need to fill grooves in valves, pumps and cylinders.

Begin with a male and female adapter, then add V-rings between them to fill the space. Each V-ring adds to the sealing force; the female adapter also has a sealing edge. For a complete seal, you need male and female adapters (sold together) and at least one V-ring

PTFE based materials: V-packing, also called vee packing, chevron packing, and parachute packing, is used in Pumps and Valves to seal the fluid or gas being moved. It's widely used in heavy duty hydraulic presses, earth moving equipments, hydraulic cranes, fork lift trucks, plunger pumps, valve actuator pistons etc.
