V-Spring Seal with PTFE jacket

200 Series:

ADVANCED V-SPRING SEAL (AVS)

The AVS spring energizer is made from flat metal strip stock and punched or chemically etched into a serpentine pattern and formed into a rounded “V” shape. The finished spring produces a moderate load versus deflection range that is suitable for most dynamic applications.

The 200 Series AVS seal produces much less friction compared to the 100 Series while being consistent with positive sealing at both low and high pressures.

The long beam leg design puts the spring load at the leading edge of the seal which allows the seal to act as a scraper or excluder seal. The 200 Series AVS seals can be supplied with an FDA approved grade of RTV silicone-filled into the spring cavity, allowing the seal to be used in food processing and clean-in-place applications.

The 200 Series AVS seals are available in all sizes to fit Industrial, Aerospace, and Military glands. Larger cross-sections up to 1/2” are also available.
