High-Pressure 20,000 PSI Hammer Union Seal and Gasket for Sour Service (H2S) with PTFE Material

High-Pressure Hammer Union Gaskets and Seals - Factory Direct

Product Overview

Material Selection and Temperature Ranges

1. NBR (Nitrile Rubber)
   Best for: General purpose water, oil, and hydraulic fluid service.
   Temperature Range: -30 degrees Celsius to +100 degrees Celsius (-22 F to +212 F).
   Characteristics: High abrasion resistance and excellent sealing properties for standard operations.

2. HNBR (Hydrogenated Nitrile)
   Best for: Sour gas (H2S) environments, crude oil, and modern drilling muds.
   Temperature Range: -40 degrees Celsius to +150 degrees Celsius (-40 F to +302 F).
   Characteristics: Superior mechanical strength and enhanced thermal stability compared to standard NBR.

3. FKM (Fluorocarbon)
   Best for: High-temperature applications and exposure to aggressive chemicals or acids.
   Temperature Range: -20 degrees Celsius to +200 degrees Celsius (-4 F to +392 F).
   Characteristics: Exceptional resistance to heat and a wide range of industrial chemicals.

4. PTFE (Polytetrafluoroethylene)
   Best for: Specialized chemical compatibility and extreme temperature scenarios.
   Temperature Range: -200 degrees Celsius to +250 degrees Celsius.
   Characteristics: Virtually inert to all industrial chemicals with very low friction.

Key Features

• Precision Lip Design: The lip geometry is optimized to utilize internal pressure to enhance the sealing force against the union wall.

• Anti-Extrusion Rings: High-pressure versions (such as Fig 1502) are available with integrated brass or stainless steel reinforcement rings to prevent the seal from extruding under extreme flow conditions.

• Factory Direct Quality: Every seal undergoes rigorous dimensional inspection and material batch testing to ensure consistent performance.

• Universal Interchangeability: Our gaskets are designed to be compatible with all standard figure hammer unions across the globe.

Application Scope

• Hydraulic Fracturing (Fracking): Maintaining seals during high-pressure sand and fluid pumping.

• Well Cementing and Acidizing: Resisting corrosive stimulation fluids.

• Oil and Gas Drilling: Essential for mud pumps, standpipes, and flowline connections.

• Mining and Industrial: High-pressure slurry transfer and large-scale water management.

• Marine and Offshore: Durable sealing for subsea and topside pipeline connections.

Technical Parameters

• Available Sizes: 1 inch, 2 inch, 3 inch, 4 inch, 5 inch, 6 inch.

• Hardness: Standard 80 to 90 Shore A.

• Media Compatibility: Oil, gas, water, drilling mud, acids, and solvents.

• Reinforcement: Optional brass or stainless steel rings for anti-washout protection.
