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...
In demanding environments where rapid gas decompression (RGD) occurs, standard O-rings can fail due to explosive pressure changes. As a leading seal manufacturer, we specialize in high-quality RGD-resistant O-rings designed to withstand extreme conditions in oil & gas, aerospace, and hydraulic systems. Our advanced elastomer compounds prevent blistering, cracking, and extrusion, ensuring long-...
Weco hammer union seals are critical components in oil and gas applications, ensuring leak-proof connections in high-pressure environments. These seals are designed to withstand extreme conditions, including corrosive fluids, temperature fluctuations, and heavy vibration. Their precision engineering minimizes downtime, making them a preferred choice for operators seeking efficiency and safety. A k...
For engineers battling space constraints in hydraulic and fluid power systems, the T-Seal Compact Seal delivers unparalleled stability and pressure resistance while fitting standard O-ring grooves. T-Seals are mostly used in stab and static applications,used for many oil and gas applications in wellhead equipment, downhole and surface applications. The T Seal has an elastomer T-shaped crossed sect...
EWT series Hammer Union Seals are static seals, which are used in hammer union-style pipe connections to establish flow lines and prevent leakage. JST provides a number of compounds compatible with mud, crude oil and chemicals with acid or H2S. JST offers two lines of hammer union seals, one from elastomer, another one from elastomer reinforced with anti extrusion ring which is normally used for h...
