OD (Outer Diameter) face seals are used on the FLS and FLS-R seat. They are a type of mechanical face seal that's used in conjunction with the ID (Inner Diameter) face seal to provide a seal between the seat and the seat pocket of FLS style valves. FLS ID and OD face seals are used in all sizes of valves ranging from 1-13/16” to 7-1/16”. The OD seal you’ll receive is spring-loaded and pressure-ene...

TFM is a modified PTFE (polytetrafluoroethylene), commonly known as white polytetrafluoroethylene. This material has excellent chemical properties and is the lowest friction coefficient among all solid materials. The wide temperature range (-200 ℃ to+260 ℃) and mechanical properties makes it a widely used universal material. TFM Modified PTFE has the same excellent chemical resistance and thermal ...

Finite element analysis (FEA) is a computer-based technique used to calculate the performance of components in practical applications. This advanced technology can determine how components are affected by extreme temperatures and pressures, specific stresses, and aggressive chemical environments. Proficient use of FEA simulations enables accurate modeling by predicting behavior, eliminating the ne...

Explosive decompression mainly occurs on materials that seal gas media, which is produced when the high-pressure gas drops to a very low pressure level in a very short time. This type of pressure reduction usually leads to damage to the seals. Elastomer materials may be torn at multiple locations or form bubbles on the surface. Explosive Decompression Testing JST is a leading manufacturer and deve...

Sour gases containing hydrogen sulfide/sulfide (H2S) can have a very adverse effect on elastomers. The elasticity that is not resistant to corrosion becomes hard and brittle, losing elasticity and sealing ability, ultimately leading to sealing failure. JST has developed various sour gas resistant elastomer materials for the oil, natural gas, and petrochemical processing industries with the third-p...

Hydraulic vee packing set is a type of packing with multiple-lip, also known as chevron seals, to prevent fluid leakage. It is typically used in adjustable gland applications such as telescopic truck hoists, pumps and valves. Vee packing sets are composed of top and bottom, male and female components, and varying numbers of center vees. The vees are arranged in a V-shape, which helps to form a tig...

PolyPak seal is a precision molded multi-purpose seal that combines an o-ring type synthetic rubber o-spring with a traditional lip seal to produce a unique sealing device capable of sealing both vacuum, high and low pressure. Traditional lip seals are prone to leakage at low pressure because the inherent lip load in basic seal design is small or non-existent. However, PolyPak is an extruded seal ...

R Rx Bx Type Metal Ring Gasket is a type of metal gasket widely used in various industrial applications. Its design object is to provide a reliable and durable seal between two flanges, ensuring that the joint remains leak free and can withstand high temperatures and pressures. The metal ring gasket types is made of various materials, such as stainless steel, carbon steel, and other alloys. The se...

T-seals are commonly used in various applications to create a reliable seal between two surfaces. In the oil and gas industry, T-seals are particularly useful in wellhead equipment as tubing hanger seals. The tubing hanger is a critical component in oil and gas wells that supports the weight of the tubing and provides a seal between the production tubing and the wellhead. T seals are three-piece s...

Spring Energized Seal consists of two components, a polymer-based seal jacket and the spring. Jackets are typically made from different PTFE material blends, which have low friction, high and low-temperature range, and broad chemical and media compatibility. The seal jacket is typically machined in the shape of a “U”. Installed with the open side of the “U” facing the system pressure.This is for t...
