Solosele® G

Our compact rod/gland seal and single‑acting piston seal with high and low pressure sealing capabilities.

  • Rod/gland seals
  • Single-acting pistons

Solosele G is a compact rod/gland seal and single-acting piston seal with excellent high and low pressure sealing capabilities that provides cost savings through reduced housing groove requirements.

It comprises a profiled elastomeric sealing element that is firmly protected by an integral anti-extrusion element of rubber-proofed fabric. High integrity sealing is enhanced by its flexible chamfered lips.

In operation, the elastomeric element provides low-pressure sealing by means of radial squeeze. As pressure increases, the pressure responsive action maintains the sealing force - even when there is significant rod misalignment.

The tough integral fabric/rubber base resists extrusion whilst being sufficiently flexible to allow recess fitting in the majority of cases.

  • Compact seal with excellent high and low pressure sealing capabilities
  • Excellent extrusion resistance for long operational life
  • Simple to fit
  • Cost savings through reduced housing groove requirements

Solosele G-AE is available with separate triangular base ring (external or internal) of PTFE, nylon or acetal to reduce friction or limit seal contact area on short-stroke applications. Dependent on whether the seal is used in a rod/gland or piston sealing application, the seal base ID or OD corner has a moulded chamfer recess in which the split anti-extrusion element/ring is positioned.

Odd-legged design is available to prevent excessive axial movement within the housing. This prevents fluid pumping under the seal lip during low-pressure rod retraction.

Rod seal for hydraulic cylinders; ram seal for hydraulic presses; or single-acting piston seal. (Two seals can be used for double-acting piston duties, but care must be taken to relieve any potential inter-seal pressure build up).

It is also suitable for slow semi-rotary applications including swivels and distributors. Additional duties include turbine blade roots, guide vanes and servo motors on hydroelectric plant - and as a static seal that offers the benefits of an 'O' ring with integral anti-extrusion capability.

  • Maximum operating pressure: 42 MPa (6092 psi)
  • Temperature range (standard materials): -20°C to +120°C (-4°F to +248°F)
  • Temperature limits (special materials): down to -45°C (-49F) with low nitrile (NBR) rubber; or up to +200°C (+392°F) with fluorocarbon (FKM)
  • Maximum surface speed (reciprocating): 0.5 m/s (98.4 fpm). For higher speeds please contact us.

Elastomeric sealing element

  • Standard material: medium nitrile (NBR) rubber
  • Special materials: low nitrile (NBR) rubber, or fluorocarbon (FKM)

Anti-extrusion element

  • Standard material: cotton fabric proofed with a blend of synthetic rubbers
  • Special materials: cotton fabric proofed with a blend of synthetic rubbers for use with low nitrile (NBR). Fabric proofed with fluorocarbon (FKM) for use with sealing element of fluorocarbon (FKM).

  • Standard materials are suitable for use with most mineral based hydraulic fluids, and most fire-resistant fluids of the water/oil or water/glycol types at temperatures up to +120°C (+248°F). They also resist air, water and most lubricating oils and greases.
  • Special materials extend considerably the range of application in terms of temperature, fluid compatibility and abrasion resistance. Please contact us for advice.

  • Supplied as standard in endless-form for optimum sealing performance
  • Standard sizes to fit piston head and rod/gland housings to BS ISO 5597 - Short (L1) and Medium (L2) axial length series and BS ISO 6020-2 are readily available. Numerous other moulds are available for non-standard sizes from 3 mm ID to 2.2 m OD. Standard inch sizes from 0.125 inch ID to 87 inch OD.
  • Other sizes within these metric and inch limits are manufactured to order, but tooling charges may be incurred. Larger diameter endless seals - to unlimited OD - can be made using our special mould-joining technique.
  • Fitting instructions are supplied with every seal
