Oil Pipe Sealing NBR HNBR FKM PTFE Hammer Union Seal Rubber Seal
Product Introduction
Hammer Union Seals are used in the connections between flexible hoses or pipes used in the oil drilling industry. The seal provides a critical fluid tight connection within the union hardware.
Hammer Unions consist of a thread end, a nut end, and a hammer nut that when tightened seal the assembly with the assistance of an elastomeric seal. The seal is lipped to prevent it from falling out when inverted.
Material Introduction
Shanghai Qinuo Industry provide NBR HNBR FKM PTFE Rubber material, they have different feature. The form for your reference:
| Material | Temperature Range | Advantage | Deficiencies |
| NBR(Nitrile, Buna-N) | -40℃ to 120℃ -40℉ to 248℉ | 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 glycol-based brack fluids and strong acids |
| HNBR | -40℃ to 160℃ -40℉ to 320℉ | 1.Nitrile based compound with improved chemical resistance 2.Wide temperature range 3.High stength material that resists extrusion, abrasion, and wear 4.Water and stream resistance to +149℃(+300℉) 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) | -26℃ to 230℃ -15℉ to 446℉ | 1.Excellent resistance to higher temperature, petroleum oils, and gasonline 2.Wide range of chemical resistance 3.Great ozone, weather, and aging resistance | 1.Poor low temperature characteriistic 2.Poor compatibility with H2S over 2%, amines, hot water and steam |
| PTFE | -268℃ to 250℃ -450℉ to 482℉ | 1.Chemical resistance, resistance to various organic solvents 2.High sealingperformance 3.anti-aging 4.Heat temperature resistance |
