Fig 1502 Hammer Union Seals: High-Pressure Sealing Solutions for Oilfield Flowlines

Reliable Sealing for Extreme 15,000 PSI Environments

The Fig 1502 Hammer Union Seal (also known as a Lip Seal) is a critical high-pressure component designed for the most demanding oilfield services. Engineered for 15,000 PSI Cold Working Pressure (CWP), these seals provide a robust, leak-proof barrier in temporary pipework, manifolds, and well-testing equipment.

As a specialized oilfield rubber seal manufacturer (SHQN), we produce Fig 1502 seals using precision-molded elastomers and high-strength metal reinforcement rings. Our seals are designed to be fully interchangeable with industry-standard union connections used in global oil and gas operations.

Key Features of SHQN Fig 1502 Union Seals

---

• Precision Fit: Molded to exact tolerances for seamless compatibility with standard hammer union joints.

• Anti-Extrusion Design: Features a bonded or snap-in metal ring to ensure seal integrity during pressure spikes.

• Chemical Resilience: Formulated to resist degradation from crude oil, fracturing fluids, and acidizing chemicals.

• Factory-Direct Supply: As a direct manufacturer, we provide wholesale pricing, material traceability, and rapid lead times.

   

Primary Oilfield Applications

---

The Fig 1502 seal is the "workhorse" of high-pressure service, widely used in:

• Hydraulic Fracturing (Fracking): Manifold trailers and discharge lines.

• Acidizing & Cementing: Ensuring leak-free connections during chemical injection.

• Well Testing: High-pressure flow back and flow control systems.

• Choke & Kill Lines: Critical safety lines on drilling and production rigs.

Frequently Asked Questions (FAQ)

---

Q1: Can your Fig 1502 seals be used in Sour Gas (H2S) environments?
A: Yes. For H2S service, we recommend our HNBR or Special Grade FKM seals with Stainless Steel reinforcement rings to prevent hydrogen embrittlement and chemical attack.

Q2: Are these seals interchangeable with standard industry unions?
A: Absolutely. Our seals are designed to industry-standard dimensions, ensuring 100% compatibility with Figure 1502 connections globally.

Q3: Do you offer bulk discounts for service companies?
A: Yes, we specialize in high-volume production and offer competitive tiered pricing for bulk orders and long-term supply contracts.
