Custom Figure 602/1002/1502/2002/2202 Hammer Union Seals: Direct Factory Supply for Oil & Gas

High-Performance Sealing Solutions for Oilfield Flowlines

---

Hammer Union Seals, also commonly known as Lip Seals, are specialized elastomeric seals used in high-pressure piping systems within the oil and gas industry. These seals are critical for maintaining a leak-proof connection in hammer union joints during demanding operations like hydraulic fracturing, cementing, and acidizing.

As a premier ISO 9001-certified manufacturer, SHQN (Royal Way) specializes in producing custom-engineered hammer union seals that are fully compatible with industry-standard figure numbers. Our seals are designed to perform under extreme mechanical stress and chemical exposure, ensuring the safety and efficiency of your oilfield assets.

Technical Parameters & Pressure Ratings (CWP)

Our hammer union seals are precision-molded to meet the strict dimensional requirements of global oilfield operations. We offer a full range of sizes (1" to 4") for the following pressure classes:

Material Performance & Selection Guide

---

Choosing the correct elastomer is vital for seal longevity. SHQN provides three primary high-grade materials to match your specific well conditions:

1. Nitrile (NBR/Buna-N)

• Best For: Standard oil, water, and drilling mud service.

• Temperature Range: -30°C to +100°C (-22°F to +212°F).

• Key Advantage: Excellent abrasion resistance and cost-effectiveness.

2. FKM (Fluorocarbon)

• Best For: High-temperature environments and aggressive chemicals.

• Temperature Range: -20°C to +204°C (-4°F to +400°F).

• Key Advantage: Exceptional resistance to heat, chemicals, and ozone degradation.

3. HNBR (Hydrogenated Nitrile)

• Best For: Sour Gas (H2S) service and high-pressure CO2.

• Temperature Range: -40°C to +160°C (-40°F to +320°F).

• Key Advantage: High mechanical strength and resistance to Explosive Decompression (AED).
