Chemical Resistant Hammer Union Seals for Harsh Environments

Product Overview

---

Our Chemical Resistant Hammer Union Seals are specifically engineered to maintain a secure, leak-proof connection in the most aggressive fluid-handling environments. Designed for high-pressure pipelines, these seals (also known as lip seals) are critical for operations involving corrosive chemicals, acidizing fluids, and sour gas (H2S). Whether in the oilfield or industrial chemical processing, our seals provide the durability and resilience needed to prevent hazardous leaks and minimize downtime.

Key Features & Benefits

---

• Superior Chemical Compatibility: Optimized to resist degradation from acids, salts, hydrocarbons, and stimulation fluids.

• High-Pressure Performance: Precision-molded to fit standard Figure 602, 1002, and 1502 unions, ensuring a tight seal up to 15,000 PSI.

• Anti-Extrusion Technology: Available with stainless steel or brass reinforcement rings to prevent seal "wash-out" under high flow rates.

• Zero Leakage Design: The pressure-energized lip geometry ensures a tighter seal as internal pressure increases.

Material Selection Guide for Harsh Environments

---

In chemically aggressive applications, choosing the right elastomer is vital. We offer high-performance materials tailored to your specific media:

1. FKM (Fluorocarbon )

• Best For: High-temperature chemical processing and exposure to aggressive acids or aromatic hydrocarbons.

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

• Advantage: Exceptional stability in hot, corrosive environments where other rubbers fail.

2. HNBR (Hydrogenated Nitrile)

• Best For: Sour gas (H2S) service, crude oil, and drilling muds.

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

• Advantage: Excellent mechanical strength combined with heat and chemical resistance.

3. NBR (Nitrile / Buna-N)

• Best For: General oil and water service with moderate chemical exposure.

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

• Advantage: Highly abrasion-resistant and cost-effective for standard operations.

4. PTFE (Polytetrafluoroethylene)

• Best For: Extreme chemical compatibility (near-universal resistance).

• Advantage: Often used as backup rings to provide a secondary barrier against chemical attack and extrusion.
