HNBR Union Gasket Seal Ring with Brass Anti-Extrusion Ring

Product Description

 

Product Description

Royal Way^®Hammer union seals are critical components used in high-pressure environments, particularly in the oil and gas industry. These seals are designed to provide robust and reliable sealing solutions for hammer union connections, which are commonly found in pipelines and high-pressure applications. The seals are known for their durability and ability to perform under extreme conditions, including high temperatures and pressures.

Material Introduction

Material name	Temperature range	Advantage	Deficiency
NBR(Buna)	-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(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, and 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 gasoline 2.Good chemical resistance, including to refrigerants(R12) 3.Great mechanical properties are retained over a wide temperature range 4.Commonly used with ammonia	Poor resistance to aromatic hydrocarbons, polar solvents, and toluene
PTFE(Plyetrafuoroethylene)	-268ºC to 250ºC -450ºF to 483ºF	Vitually universal chemical resistance	Generally more expensive than other plastics or elastomers, which can be a limitation for cost-sensitive applications.
PU (Polyurethane)	-54°C to 105°C  -65°F to 220°F	1.Thermoplastic elastomer with higher tensile strength, toughness, and wear resistance 2.Great combination of hardness and elasticity 3.Excellent low temperature flexibility 4.Commonly used in high pesure hydraulic systems where parts are subject to wear	Can degrade when exposed to UV light over prolonged periods unless specifically formulated with additives for protection.
