Piston seal maintain sealing contact in sliding motion between the piston and cylinder bore.
Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5,800 psi). The pressure acting on the piston seal increases contact forces between the piston and cylinder surface. Therefore the surface properties of the sealing surfaces are critical to proper seal performance.
Piston seals are typically classified into single acting (pressure acting on one side only) and double acting (pressure acting on either side) seals.
Sealing Australia stocks the following profiles:
GH and GHM profiles have a nitrile (NBR) rubber o’ring energiser and a bronze filled PTFE sealing element. Square ring and Viton energiser are available on request. There profiles are suitable for pressures up to 400 bar (5,800 psi) and are available in metric sizes. Some metric sizes fit seal housing in accordance to ISO 7425-1.

MD-L profiles have a nitrile rubber sealing element with polyester thermoplastic elastomer anti-extrusion rings, which incorporate polyacetal guide rings. The sealing element serves as a slide ring and also seals statically against the seal groove. The anti-extrusion rings support and protect the sealing element against gap extrusion. Both the guide and anti-extrusion rings are split to ease installation. MD-L profiles are suitable for pressures for pressures up to 250 bar (3,625 psi) and are available in metric and imperial sizes. Some metric sizes fit seal housings in accordance to ISO 6547.

Designed to fit imperial o’ring housings in accordance to ISO3601 (BS1806/AS568A o’ring sizing), T-seals are an ideal replacement for o’rings. The T-shaped sealing element serves as a slide ring that’s highly resistant twisting and spiral failure. Piston T-seals seal statically against the groove ID and are suitable for pressures up to 345 bar (5,000 psi).
MPT profiles have a nitrile (NBR) rubber sealing element and hard polyamide, non-locking anti-extrusion rings.
