Standard Fig 602, 1002, 1502 Hammer Union Seals for Sale NBR HNBR FKM PTFE

Product Introduction

---

High-performance Hammer Union Seals (also known as Lip Seals) are critical components used in the oil and gas industry to create a high-pressure, leak-proof connection between hammer union pipe fittings. Our seals are manufactured to industry-standard dimensions for Fig 602, Fig 1002, and Fig 1502, ensuring perfect compatibility with your existing pipeline systems.

Material Performance Comparison

---

Selecting the correct elastomer is vital for the longevity of your hammer union seal. Below is a comparison based on working environments:

• NBR (Nitrile / Buna-N):

  • Application: General purpose water, oil, and mud service.

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

  • Pros: Cost-effective, excellent abrasion resistance.

• HNBR (Hydrogenated Nitrile):

  • Application: Modern drilling, crude oil, and sour gas environments.

  • Temperature Range: -40°C to +150°C (-40°F to +302°F).

  • Pros: High mechanical strength, superior heat and H2S resistance.

• FKM (Fluorocarbon ):

  • Application: High-temperature chemical processing and aggressive fluids.

  • Temperature Range: -20°C to +200°C (-4°F to +392°F).

  • Pros: Exceptional chemical stability and heat resistance.

• PTFE :

  • Application: Extreme chemical exposure and cryogenic or high-heat scenarios.

  • Pros: Near-total chemical inertness and very low friction.

Working Pressure by Figure Number

---

Our seals are engineered to withstand the specific pressure requirements of each figure:

• Fig 602 Seals: Designed for pressures up to 6,000 PSI.

• Fig 1002 Seals: Designed for pressures up to 10,000 PSI.

• Fig 1502 Seals: Heavy-duty design for high-pressure service up to 15,000 PSI.

Key Features & Advantages

---

• Precision Fit: Molded to exact tolerances for "standard figure" unions to ensure zero-leak performance.

• Anti-Extrusion Design: Available with metal reinforcements (brass or stainless steel) to prevent seal "wash-out" under high-pressure flow.

• Chemical Resilience: Optimized compounds to resist degradation from acids, salts, and hydrocarbons.

• Reliable Sealing: Maintains elasticity and sealing force even during rapid pressure fluctuations.

   

Common Applications

---

Our Hammer Union Seals are widely used across global oilfields and industrial sectors:

• Oil & Gas Flowlines: Connecting pipes during drilling and production.

• Fracking Operations: High-pressure hydraulic fracturing fluid transport.

• Acidizing & Cementing: Secure seals during well stimulation and casing.

• Mud Systems: Handling abrasive drilling mud in suction and discharge lines.

• Water Transfer: Large-diameter water pipelines in industrial sites.
