This double o-ring piston head is machined from the structural plastic TECAFORM, also known as POM.
Nine holes are drilled on the front side to allow the negative pressure to quickly equalize, reducing friction on the rear stroke, and helps expand the o-ring on the forward stroke.
The centre of the piston head is clamped by a lock nut, which spreads the force over a larger area and prevents breakage of the bolt from the body of the piston head.
This piston head also incorporates an axial ball bearing.
Advantages:
- High resistance
- Perfect sealing + guide rings
- Axial ball bearing for easy spring rotation
- Plastic nut that reduces total weight
