Bonded Seal Test: Ensuring Reliable Sealing Performance. What is a Bonded Seal? Bonded seals are widely used in industries such as oil & gas . A bonded seal consists of a metallic with a vulcanized elastomer sealing. The combination of rigid support and flexible sealing ensures high pressure resistance and leak-tight performance. Key Tests for Bonded Seals To ensure performance, these seals un...
ID/OD Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life. It is an end face mechanical seal with both rigid and flexible elements, which gives consistent contact at the sealing interface. ID face seals and OD face seal are combined used for valves. JST ID/OD face seal is spring loaded with a pressure energized lip seal. It is...
In high-pressure hydraulic and pneumatic systems, the primary seal faces a relentless enemy: extrusion. Under extreme pressure, the sealing material is forced into the microscopic gap between the piston and the cylinder wall (or the rod and the housing). This deformation, known as extrusion, leads to nibbling, tearing, and ultimately, seal failure. This is where the critical role of a back-up ring...
In liquefied natural gas (LNG) applications, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). The equipment faces constant thermal cycling, conventional seals risk failure, leading to dangerous leaks and operational shutdowns. Lip seals excel in these extremes by maintaining elasticity and sealing integrity even under cryogenic...
The one-piece S-Seal eliminates installation problems that can occur when using multiple component seals. It can be stretched into place without splitting or compromising the non-extrusion elements of the seal. S-seal sealing materials need to withstand pressures as high as 20 000 psi and temperatures of 177º C (350º F). JST S-seal is made to perform in toughest situations, delivering reliable hig...
Leakage in hammer union connections is more than a nuisance; it's a serious safety hazard, an environmental risk, and a major source of non-productive time (NPT) on the rig. While the hammer union itself is a robust and trusted component, its performance is entirely dependent on a single, often overlooked part: the seal. Standard seals can extrude, crack, or degrade when exposed to high-pressure H...
Hydraulic rod applications face relentless challenges: high-pressure spikes, side loads, abrasive contaminants, and temperature extremes. Traditional elastomeric seals often crack, extrude, or leak under these conditions—causing downtime and fluid loss. SPNS type hydraulic seals, are also call rod buffer step seals, static seals installed in glands or housings to prevent the leakage of fluid from ...
In LNG terminals, liquid nitrogen systems, and cryogenic pipelines (-196°C), standard elastomer seals fail catastrophically—brittle fractures, shrinkage-induced leaks, and cold flow compromise safety. As a leading cryogenic seal manufacturer, we engineer PTFE and PEEK ball valve seat seals specifically for sub-zero environments. Our materials resist thermal shock, maintain elasticity at -196°C, an...
Hydraulic systems demand precision sealing under extreme pressure, temperature shifts, and contamination. Standard rubber seals often fail through extrusion, swelling, or wear—leading to costly leaks and downtime. The SPGW seal is specially designed for heavy hydraulic equipment and includes a Teflon mixture outer ring, a rubber inner ring and two POM backup rings. The rubber elastic ring provides...
When aggressive chemicals, ultra-high temperatures, or ultra-high purity environments threaten standard elastomers, FFKM O-rings and seals deliver unparalleled performance. As a leading manufacturer of high-integrity sealing solutions, we specialize in perfluoroelastomer (FFKM) components engineered to withstand conditions where FKM and PTFE reach their limits. FFKM’s near-universal chemical compa...
