4" NBR PTFE FKM Pipeline Tubing Union Seals for Gas and Oil

Product Description

High-performance Hammer Union Seals are sealing components used to ensure the connection between hammer unions is completely leak-proof. They are critical in high-pressure applications, where leakage can cause operational failure or environmental damage.
Union seals are made from high-performance materials like rubber and elastomers that can endure extreme conditions.They are widely used in the oil, gas, and chemicalindustries to ensurereliability under extreme conditions.

Material name	Temperature range	Advantage	Deficiency
NBR (Buna/Nitrile)	-40ºC to 120ºC -40ºF to 248ºF	1.Presently the most widely used rubber in the seal industry 2.Exceptional balance of good mechanical properties, wear properties, and chemical resistance 3.Resistance to most mineral oils and greases	don't used with gly-based brake fluids and strong acids
HNBR (HSN/ Hydrogenated Nitrile)	-40ºC to 160ºC -40ºF to 320ºF	1.Chemical resistance 2.Wider temperature range than standard nitrile 3.High strength material that resists extrusion, abrasion, wear 4.Water and steam resistance to +149ºC(+300ºF) 5.H2S resistance up to 10% 6.Commonly used with petroleum oils and co2	don't use with chlorinated hydrocarbons, polar solvents, or strong acids
FKM (Fluorocarbon)	-26ºC to 230ºC -15ºF to 446ºF	1.Excellent resistance to higher temperature, petroleum, and gas oline 2.Good chemical resistance, including to refrigerants(R12) 3.Great mechanical properties are retained over a wide temperature range 4.Commonly used with Am monia	Poor resistance to aromatic hydrocarbons, polar solvents, and to luene
PTFE (Plyetrafuoroethylene)	-268ºC to 250ºC -450ºF to 483ºF	Vitually universal chemical resistance	High cost, relatively low mechanical strength, machining difficulty
