Product Description
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.
Common Hammer Union Types include Threaded Hammer Unions (40, 50, and 602 to 1502),Butt Weld Hammer Unions (602, 1502, and 2202),Threaded & Butt Weld Hammer Unions (100 to 400)
We currently mainly provide union seals suitable for FIG1502, FIG1002, FIG602, FIG 206, FIG607 styles. And other types we can customize according to samples or drawings
About Union Seal, we can provide:
| TYPES | FEATURE |
| Union seal with brass ring | The use of brass rings can increase the tightness of the seal, prevent leakage, and maintain stable performance in long-term use, extending the service life. In addition, the corrosion resistance of brass can also ensure that the sealing effect is maintained in various environments, especially in weak acids, weak alkalis and salt water. |
| Union seal with stainless steel ring | It has high corrosion resistance and can resist corrosion from weak corrosive media such as air, steam, water, and chemical substances such as acid, alkali, and salt. The strength and corrosion resistance of stainless steel vary with the alloy elements, and it has high heat resistance and wear resistance. |
| Rubber union seal | Rubber seals have good elasticity and compression memory, and can adapt to a wide range of temperatures, from extremely low temperatures to high temperatures. Their manufacturing cost is relatively low, making them suitable for large-scale production and application. In low-pressure, low-temperature and normal temperature environments, rubber seals usually have better sealing effects than metal seals. |
