Bulk Figure 602/1002/1502 Hammer Union Seals Manufacturer for Oilfield Applications
Introduction to High-Performance Hammer Union Seals
Hammer Union Seals (also known as Lip Seals) are critical components used in the oil and gas industry to ensure leak-free connections between hammer union joints. Designed to withstand extreme pressures and harsh chemical environments, these seals are essential for high-pressure flow lines, fracturing, acidizing, and cementing.
As a leading ISO9001 certified rubber seal manufacturer, SHQN (Royal Way) provides premium-grade hammer union seals that are fully interchangeable with standard industry figure numbers. Our seals are engineered to provide a tight, dependable seal even in the most demanding oilfield conditions.
Technical Specifications & Working Pressure
Our hammer union seals are available in various sizes (1” to 4”) and configurations to match specific service requirements.

Material Comparison: Choosing the Right Elastomer
The performance of a hammer union seal depends heavily on the material. At Qinuo (SHQN), we offer three primary elastomers to suit different oilfield mediums:
1. Nitrile (NBR/Buna-N)
-
Temperature Range: -30°C to +100°C (-22°F to +212°F)
-
Best For: General oil and water service, drilling mud, and hydraulic fluids.
-
Advantage: Cost-effective, excellent abrasion resistance.
2. FKM / Fluorocarbon
-
Temperature Range: -20°C to +200°C (-4°F to +392°F)
-
Best For: High-temperature applications and aggressive chemicals.
-
Advantage: Superior resistance to heat, chemicals, and ozone.
3. HNBR (Hydrogenated Nitrile)
-
Temperature Range: -40°C to +150°C (-40°F to +302°F)
-
Best For: Sour Gas (H2S) service and high-pressure CO2 environments.
-
Advantage: Exceptional mechanical strength and wear resistance.
