SPGW Piston Seal – the workhorse of heavy-duty hydraulics. 🔧

When your excavator cylinder runs long strokes under high pressure, you need a seal that keeps up. The SPGW delivers:

✅ Bronze-filled PTFE slide ring – low friction, no stick-slip
✅ NBR energizer – keeps sealing force consistent
✅ Twin POM back-up rings – fights extrusion at pressure peaks
✅ Handles up to 50 MPa – built for the real world
✅ Wide temp range: -30°C to +120°C

Compact groove. Simple install. Long service life. That’s why it’s the go-to for excavator boom, arm, and bucket cylinders. 🏗️

📐 Metric sizes available – in stock & ready to ship.
📩 DM your cylinder size – we’ll match it for you.

Why do hydraulic cylinders fail? Often, it starts with the wear ring. 🤔

Metal-to-metal contact → scoring → leakage → downtime.

Our Phenolic Resin Wear Ring solves it:

✔️ Absorbs side loads – protects piston & rod
✔️ High-strength phenolic resin – tough under pressure
✔️ Self-lubricating – low friction, smooth movement
✔️ Resists heat, oil & wear – long service life
✔️ Fits excavators, cranes, industrial hydraulic systems
