V-rings

PTFE V-rings provide a durable, dimensionally stable seal for demanding hydraulic and pneumatic applications.
Several sealing lips ensure high sealing performance – ideal for plunger, piston and valve systems.

V-rings made of PTFE and other high-performance plastics

PTFE V-seal sets consist of a pressure ring, a back-up ring and V-rings that are adapted to the respective operating conditions. Thanks to their dimensional stability and adjustable preload, they remain reliably tight even under pressure peaks. They offer low breakaway forces after standstill and are insensitive to contaminated media. Depending on the application, versions in pure or filled PTFE are available – elastic for low pressure, sealing by wedge effect for versatile use, or pressure-resistant for harsh operating conditions. As they are machined, many diameter and height variants are possible.

Material overview

Low-pressure V-seal set (NDM)
– Pressure range: < 50 bar
– Elastic profile design
High-pressure V-seal set (HDM)
– Pressure range: 50 to 100 bar
– Relatively rigid profile, seals by wedge effect
Extreme-pressure V-seal set (HöDM)
– Pressure range: 100 bar – 250 bar
– Preferably for static sealing functions and pulsating pressures
