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. Match the replacement seal to the actual union manufacturer, figure, nominal size and groove for fracturing, cementing or acidizing service.

As a premier ISO 9001-certified manufacturer, SHQN (Royal Way) supports drawing-based hammer union seal replacement. Confirm fit, compound and service requirements for each union configuration.

Technical Parameters & Pressure Ratings (CWP)

---

Listed nominal size references are 1", 2", 3" and 4". Confirm each figure-size combination against the manufacturer drawing. Pressure belongs to the complete identified union assembly, not the replacement rubber alone; the table is a configuration reference requiring assembly documentation.

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: Confirm continuous and peak limits for the selected NBR compound.

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

•  
•  
•  

2. FKM (Fluorocarbon)

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

• Temperature Range: Confirm continuous and peak limits for the selected FKM compound.

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

•  
•  
•  

3. HNBR (Hydrogenated Nitrile)

• Best For: Gas-Service Enquiries require the actual H2S / CO2 composition or partial pressures, temperature, pressure cycles and decompression conditions. Confirm exact-compound qualification before selection.

• Temperature Range: Confirm continuous and peak limits for the selected HNBR compound.

• Key Advantage: Specify mechanical-property and decompression qualification requirements for the exact compound.

Frequently Asked Questions (FAQ)

---

Q: Are your seals compatible with industry-standard hammer unions?
A: Confirm the union manufacturer, figure, nominal size and seal drawing before replacement; figure number alone does not establish interchangeability.

Q: Can you provide materials for H2S (Sour Gas) service?
A: Absolutely. We offer specialized HNBR and FKM compounds for review against the actual gas composition, temperature, pressure and qualification requirements.

Q: Do you offer custom sizes or branding?
A: Yes, we provide OEM services and can manufacture custom sizes or materials based on your technical requirements or samples.

Q: What is the lead time for bulk orders?
A: Confirm lead time after the figure, size, compound, construction and order quantity are agreed.

Custom Figure 2002 and 2202 Seal Drawing Review

Identify Figure 2002 and Figure 2202 separately when ordering. Provide the manufacturer marking, nominal size, groove drawing and photographs of the existing seal faces and side profile. Confirm the lip and backup construction, compound, hardness and tolerances. Include medium, temperature, pressure and gas-service requirements. Approve the specific replacement configuration before repeating the order.
