Authorized Distributor for Parker O-Rings
O-Rings and Accessories
Parker Hanifin O-rings in hundreds of compounds, plus essential accessories including installation tools, lubrication, and storage solutions for optimal performance.
Piston Seals
High-performance seals designed to prevent fluid bypass in hydraulic and pneumatic cylinders, engineered for extreme pressure/temperature applications.
Vulcanized & Spliced Gaskets
Vulcanizing uses heat, pressure, and uncured rubber to bond the two ends into a continuous part. Applications include O-rings, tubing, and other products with a space for the free-flowing passage of air to the gasket. GSF is well-known for vulcanizing electric transformer gaskets.
Specialty Gaskets
We also offer a wide variety of specialty rubber gaskets: lathe cut, extruded, molded, and many more!
Static Seals
Custom-fabricated seals for stationary applications, including flange gaskets, cover seals, and housing gaskets in materials ranging from basic elastomers to exotic compounds.
Valve Seals
Critical sealing components for industrial valves, including seat seals, stem seals, and bonnet gaskets designed for zero-leakage performance.
Engineered Seals Experts for 50 Years
Back-up Rings
Essential support components that prevent seal extrusion under high pressure, available in PTFE, PEEK, and other high-strength materials.
Buffer Seals
Specialized Parker seals that protect primary sealing elements from pressure spikes and contamination in demanding hydraulic applications.
Cushioning Seals
Impact-absorbing seals designed to reduce system shock and vibration while maintaining effective sealing performance.
Fastener Seals
Precision sealing solutions for bolted connections, including crush washers, bonded seals, and specialty fastener gaskets.
Flange Seals
Custom-fabricated flange gaskets in full face, raised face, and RTJ configurations, designed for critical pipeline and pressure vessel applications.
Spacers
Precision-cut spacers and shims in metallic and non-metallic materials, engineered to exact tolerances for proper component alignment and spacing.
