Frequently Asked Questions

A V-packing is used to seal moving components such as pistons or rods. Its shape allows it to expand under pressure, creating a tight seal that prevents fluid leakage while allowing smooth motion.

This packing is typically installed inside the packing stack of a pump fluid section, sealing the rod or piston during reciprocating operation.

Compatibility should be confirmed by checking the equipment parts manual or matching the packing dimensions with the existing seal in your pump assembly.
