PTFE V-Packings

PTFE V-Packings for OEM, Valves, Pumps, Mixers and Agitators



PTFE V-packings are manufactured using either a manual lathe a CNC lathe,  or a molding process.  Each process has its advantages and disadvantages.  In general molded parts are cheaper to produce, but require longer lead times and bigger commitments. Manual Lathes ar great for quick one-time sets, and CNC balances high production and quick turnaround times.  AS&P offers all three methods of producing PTFE V-Packing.  Other terms for this product is PTFE Vee or PTFE Chevron Packing.

There are three critical dimensions you need to know when looking for v-packing. You must know the Inside dimension (best taken off the shaft you are trying to seal), The outside dimension (best taken from the bore the set will be placed into) and the stack height.  Generally slightly less than the height of the stuffing box.

Once we have those 3 dimensions, we will need to determine how many V-rings (also called pressure rings), are required to give you your desired stack height.

Finally, we will need to know if you need the male and female (top & bottom) to complete the set. Many pumps and valves come with the make and female made from metal already.

PTFE V-Packings:

Are Exceptional in Chemical Applications, Cyrogenic applications, Clean service (FDA) applications. Because PTFE has the lowest coeffiecient of friction, it lowers stem drag allowing valves to turn easier. If your looking for a less expensive option we also offer other materials such as Nitrle, Viton, Neoprene, Grafoil

Standard Sizes Available:

We supply both molded and machined PTFE parts. Custom sizes to match competitor styles are available. Please specify I.D. / O.D. and stack height desired when ordering.

Typical installations:

Rubber & Fabric V-Packing

The above set is an example of our v-pressure rings combined with equipment supplied metal end rings (Aluminum bronze in this example).


Molded PTFE V-packing

When PTFE is molded it will often have a shiny surface. That and the lack of very fine cutting lines left by a lathe can help you tell how they were made.

Mechanical Seals

What are the most common applications for V-Packing?

V-Packing or Vee Packing if you prefer is commonly used in valves, reciprocating Pumps, centrifugal pumps, mixers, agitators, and actuators. The industries they are used in include but are not limited to food (PTFE is FDA application compatible), chemical (PTFE has a 0-14 ph range), oil, gas, pulp and paper, water, wastewater, power generation, the list goes on. Many of the PTFE V’s we sell go into original equipment manufacturers’ products.
