100Standard size hammer union seal
Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.
The hammer connector for high-pressure equipment has a replaceable lip seal in the female connector. It provides critical fluid tight connections within the union hardware.
Materials available include NBR, HNBR, Viton. In addition to the standard molded rubber seals, anti-extrusion rings can be reinforced in brass Hammer Union Seals or stainless steel Hammer Union Seals.
This type is particularly suitable for abrasive high pressure (15000 psi) hammer unions that do not require welded connections. This design provides a strong, permanent end connection without butt welding. The end of the joint is assembled to the pipe in the workshop. Epoxy thread compound is used for fixed connections. Since all threads are isolated from the fluid line, the resulting smooth holes ensure minimum turbulence, reduce flushing and reduce the accumulation of acid, sand, cement or chemicals around the pipe end.

Hammer Union Seals help to prevent leakage in hammer union pipe connections and are generally applied in applications within the Chemical Processing, Offshore Drilling, Petrochemical, and Water and Gas industries.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
Wellhead secondary pack off seal is used to seal the hanger to the wellhead.
BT Seal is a static seal that is used to seal rough casing and tubing. It is constructed from an elastomer with anti-extrusion spring bonded within it. Springs are available in stainless steel, elastomer could be HNBR or NBR.
VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders.
The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.
BS seal is rod seal for hydraulic cylinders, single-acting, polyurethane u-cup design with secondary sealing lip.
