View specificationsHelicoil Spring
M01–M10 radial and axial seals with medium to high spring load — positive sealing for medium to high pressures and cryogenic duty.
Explore helicoil sealsRounded U Spring
M20–M29 low-load, high-deflection seals for low-friction rod and piston duty, tolerant of eccentricity and misalignment.
Explore rounded U-springPointed U Spring
The M60 range — the pointed U-spring profile widely used across industry, in any Moontown jacket and spring material combination.
Explore pointed U-springU Finger Spring
M30/M31 heavy-duty axial face seals for extreme conditions: cryogenics, ultra high vacuum, thin gases and loading arm swivels.
