Hydraulic Seal

Custom Spgw PTFE Piston Seal for Hydraulic Cylinder and Pump

SPGW SPGW is for reciprocated hydraulic systems. Possesing excellent performance if applied at heavy load and double sealing under high pressure working conditions. Particularly suitable for long stroke, large range of fluids and high temperature circumstance . Applicable for bigger piston gap. Simple groove structure. Standard Materials: Sealing ring: filled with polytetrafluoroethylene (F-PTFE) Elasticity: nitrile rubber (NBR) Backup ring: modified polyoxymethylene (POM) or modified nylon (PA) Features: • Excellent sealing performance in both dynamic and static conditions • Allows for larger extrusion gaps, reducing processing costs depending on the application • Can be safely used in Medium with contaminants due to the larger extrusion gaps • Low friction and no crawling phenomenon • Simple groove design, suitable for integral pistons • If there are special requirements (pressure, temperature, speed, special Medium, etc.), please contact our consulting service department for recommendations on suitable materials. Technical Specification: • Pressure: 50 MPa • Speed: 1.5 m/s Code Fucntion Limited Condition Pressure (MPa) Speed (m/s) Temp.

Seals should be kept aw ay from heat sources like direct sunlight and heat-emitting objects . The maximum storage temperature is +32°C. Low temperatures w on't cause permanent damage to the seals but can make them brittle, leading to potential breakage if mishandled. Generally , the storage temperature for seals should not go below +10°C, and they should be brought to room temperature before installation. Avoid strong light Surfaces should be shielded from direct sunlight and artificial light s
