Heavy Duty Piston Sealing Design
Designed for hydraulic cylinder piston sealing under high pressure and heavy load working conditions.
Double Acting Sealing Performance
Suitable for bidirectional hydraulic cylinders, providing stable sealing in both working directions.
F-PTFE Sealing Ring Structure
The F-PTFE sealing ring offers low friction, good wear resistance, and smooth reciprocating movement.
NBR or FKM O Ring Energizer
The O ring provides reliable elastic support and helps maintain stable sealing force during operation.
PA or POM Check Ring Support
PA or POM check rings improve anti-extrusion performance and protect the seal under high pressure.
Low Friction and Smooth Motion
Helps reduce stick-slip, lower starting resistance, and improve hydraulic cylinder movement stability.
Good Anti-Extrusion Ability
Compact multi-part structure helps prevent sealing material extrusion in high-pressure applications.
Suitable for Large Hydraulic Cylinders
Commonly used in excavators, cranes, loaders, mining machinery, presses, and industrial hydraulic equipment.
Custom Sizes and Materials Available
Can be customized according to groove size, working pressure, temperature, medium, and application conditions.
Stable Performance in Hydraulic Oil
Suitable for common hydraulic oil systems, offering reliable sealing and long service life in demanding equipment.

AI-Powered supplier vetting
SummaryThe supplier demonstrates established manufacturing activity, four production lines, flexible customization, documented quality and complaint-handling procedures, and ISO9001:2015 certification. It offers inventory capability, multiple quotation and payment options, and has participated in PTC ASIA. However, its export experience is only one year, its primary export market is stated as domestic, and it reports no overseas agents, branches, warehouses, or showrooms. Manufacturing capacity lacks a valid contract with related subcontractors. Innovation evidence is limited: two R&D engineers are reported, but no SDK is available. The supplier confirms OEM service for well-known brands but provides no named customer cases or Fortune 500 cooperation.
CertificationsISO9001:2015 certification is explicitly reported for management, quality assurance, and sustainable-development-related systems. This supports a documented quality-management framework, although no other certifications are identified.
After-Sales capabilityThe supplier has a documented customer-complaint procedure with followed records and a corrective/preventive-action mechanism. However, it has no overseas agents or branches, warehouses, or showrooms, so the evidence supports process capability but not broad overseas service coverage.
Production capacityManufacturing capability is supported by the supplier’s stated industry experience, four production lines, inventory capability, one-month peak and off-season lead times, written inspection procedures, and quality assurance. A material limitation is that no valid manufacturing-capacity contract exists with related subcontractors.
Customization capabilityThe supplier explicitly supports customization from samples, designs, minor customization, and flexible customization. This is direct evidence of broad customization availability.
Product Q&A
Q:What is SPGW Piston Seal used for?
A:
SPGW Piston Seal is used for hydraulic cylinder piston sealing. It is mainly applied in double acting hydraulic cylinders for construction machinery, mining equipment, press machines, cranes, loaders, and other heavy duty hydraulic systems.
Q:What is the material of SPGW Piston Seal?
A:
The standard structure is F-PTFE sealing ring + NBR O Ring + PA or POM check rings. FKM O Ring and other material combinations can also be customized according to working conditions
Q:Is SPGW Piston Seal suitable for double acting cylinders?
A:
Yes. SPGW Piston Seal is designed for double acting and bidirectional sealing, making it suitable for piston applications where pressure acts from both directions.
Q:What is the maximum working speed?
A:
The recommended working speed is up to 1.5 m/s, depending on hydraulic oil, surface finish, pressure, and cylinder working environment.
Q:What size range can you produce?
A:
We can produce SPGW Piston Seal in the common size range of 50 to 500 mm. Custom sizes can also be made according to drawings or samples.
