Rod and Buffer Seals

Rod seals are typically single-acting seals, which means fluid pressure acts from inside the cylinder on one side of the seal only. Buffer seals protect the rod seals by reducing pressure peaks (sudden pressure spikes).

Rod Seals

Rod seals are typically single-acting seals, which means fluid pressure acts from inside the cylinder on one side of the seal only. Pressures acting on the rod side of the seal can be in excess of 400 bar (5,800 psi), pressure peaks can be even higher. The pressure acting on the rod seal increases contact forces between the rod seal and cylinder surfaces. Therefore, rod seal materials should be wear resistant and the rod surface needs to be manufactured to the recommended specifications.

Buffer Seals

Buffer seals protect the rod seals by reducing pressure peaks (sudden pressure spikes). Abrupt pressure peaks can occur by external forces acting on the piston rod initiated by the fluid inside the cylinder. These pressure peaks can be far in excess of the system operating pressure. Buffer seals in combination with rod seals provide an effective rod sealing system for cylinders in heavy duty applications at high temperature and pressure.

SIL: Rod U-Cup

SIL profiles are made of ether based polyurethane and have a double lip design. They provide good resistance to hydrolysis (attack from moisture) and good low temperature resilience. These profiles are suitable for pressures up to 350 bar (5,075 psi) for light to medium duty applications and are available in metric sizes only.

  • Material: TPU
  • Pressure: 350 bar (5,075psi)
  • Speed: ≤0.5 m/s (1.6 ft/s)
  • Classification: Light to medium duty
  • Sizing: Metric

RBB: Rod Buffer

RBB profiles have a self lubricating seal ring that incorporates a polyimide (PA) or polyacetal (POM) anti-extrusion ring. The flexible outside static sealing lip and channels in the front face ensure that pressure can return to the system side of the buffer and prevent build up of pressure between the rod and buffer seals. These profiles are suitable for pressure peaks and demanding workloads in heavy duty applications up to 690 bar (10,000 psi).

  • Material: TPU/PA
  • Pressure: 690bar (10,000psi)
  • Speed: ≤1 m/s (3.2 ft/s)
  • Classification: Medium to heavy duty
  • Sizing: Metric and Imperial

S9B: Rod Glide Ring Buffer

S9B profiles have a nitrile rubber o’ring energiser and a bronze filled PTFE slide ring as standard. Depending on the application, the slide rings can be manufactured from a variety of PTFE and polyurethane materials for improved chemical resistance, wear resistance and ease of installation. S9B profiles with a PTFE slide ring are suitable for pressures up to 400 bar (5,800 psi).

  • Material: TMB/NBR
  • Pressure: 400bar (5,800psi)
  • Speed: ≤2 m/s (6.5 ft/s)
  • Classification: Light to heavy duty
  • Sizing: Metric and Imperial

Rod T Seals

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. Rod T-seals seal statically against the groove OD and are suitable for pressures up to 345 bar (5,000 psi).

MRT: Rod T Seal

MRT profiles have a nitrile (NBR) rubber sealing element supported by hard polyamide non-locking anti-extrusion rings.
