PTFE Seals / V Seal/ U Seal/ Spring Seal/ V Piston Ring

HONY®PTFE Seals / V seal/ U seal/ Spring seal/ V piston ring

Cantilever spring The V-shaped cantilever spring shows a moderate load versus deflection. The long beam-leg design puts the spring load out at the leading edge of the seal - right on the sealing edge.
The wide range of flexibility of the spring allows to compensate for some deviation in the gland tolerances and seal wear.

Recommended applications:
- Dynamic rod and piston seals
- Rotary seals

Helical spring
The helically wound ribbon spring shows a high load versus deflection.

The load of the helical spring is provided directly through its centre line. Due to the low selection range,
the helical spring is not suitable for applications with wide gland tolerances or eccentricity.

Recommended applications:
- Static/Semi-static applications
- Low temperatures
- In very slow or infrequent dynamic conditions when friction and wear are secondary concerns to positive sealing
