The SPGO‑type double‑acting piston seal is a high‑performance hydraulic sealing component specially engineered for piston applications, delivering reliable sealing performance in both forward and reverse movement directions inside hydraulic cylinders. Built from premium polyurethane and PTFE composite materials, this piston seal balances outstanding wear resistance, low‑friction operation and excellent pressure resistance, making it ideal for heavy‑duty hydraulic systems that require stable bidirectional sealing effect.
Thanks to its optimized cross‑section profile, the SPGO double‑acting piston seal maintains consistent pre‑tightening force under fluctuating working pressure, effectively preventing internal oil leakage within cylinder assemblies. It resists extrusion under high‑pressure impact and tolerates a wide temperature range, adapting well to mineral hydraulic oils and most common industrial fluid media. Simple to install into standard piston grooves, it fits well for mass assembly and aftermarket replacement.
Widely adopted in construction machinery, agricultural equipment, hydraulic presses and industrial hydraulic cylinders, the SPGO‑type piston seal cuts down maintenance frequency and extends cylinder service life. Manufacturers, distributors and equipment repair suppliers can rely on this robust bidirectional seal to solve piston leakage troubles in diverse heavy‑load working conditions.
