Leak-Proof Oilfield Hammer Union Seal with High Pressure Resistance and Material Versatility for Fracking Equipment

Oilfield Hammer Union Seals: Leak-Proof Fracking Equipment Seals

Product Overview

High-quality Hammer Union Seals are critical components in the oil and gas industry, specifically designed to provide a secure, leak-proof connection in high-pressure piping systems. These seals are used within hammer unions during hydraulic fracturing (fracking), acidizing, cementing, and other well-service applications.

Our seals are engineered to withstand extreme vibrations, abrasive fluids, and massive pressure spikes, ensuring operational safety and minimizing downtime in the field.

Key Features and Benefits

1. Superior Leak Prevention: Precision-molded to fit standard high-pressure union configurations, ensuring a tight seal even under fluctuating pressures.
2. High Pressure Resistance: Specifically designed for heavy-duty service environments.
3. Material Versatility: Available in various elastomers to suit different chemical and temperature requirements.
4. Extrusion Resistance: Some models feature a stainless steel or brass backup ring to prevent the seal from extruding under extreme pressure.
5. Easy Installation: Designed for quick replacement in the field to keep your fracking operations running smoothly.

Technical Specifications

Working Pressure:
Our hammer union seals are rated for various pressure classes, commonly used in:
High Pressure: 6,000 PSI to 15,000 PSI (Compatible with Fig 602, 1002, 1502 types)
Ultra High Pressure: Up to 20,000 PSI (Compatible with Fig 2202 type)

Temperature Range:
Standard NBR: -30 Celsius to +100 Celsius (-22 Fahrenheit to +212 Fahrenheit)
High-Temp FKM: -20 Celsius to +200 Celsius (-4 Fahrenheit to +392 Fahrenheit)
Low-Temp HNBR: -40 Celsius to +150 Celsius (-40 Fahrenheit to +302 Fahrenheit)

Material Comparison and Selection

1. Nitrile (NBR / Buna-N)
Best For: Standard oil and water service.
Advantages: Excellent abrasion resistance, cost-effective, good oil resistance.
Limitations: Poor resistance to high temperatures and harsh chemicals.

2. FKM ( Fluoroelastomer)
Best For: High-temperature and chemical-heavy environments.
Advantages: Superior heat resistance and excellent resistance to acids, fuels, and solvents.
Limitations: Not ideal for extreme low-temperature applications.

3. HNBR (Hydrogenated Nitrile)
Best For: Sour gas (H2S) service and heavy-duty fracking.
Advantages: Extremely tough, better heat resistance than standard NBR, and resistant to CO2 and H2S.
Limitations: Higher cost than standard Nitrile.

4. PTFE (Teflon) with Elastomer Core
Best For: Extreme chemical resistance.
Advantages: Virtually inert to all chemicals.
Limitations: Less "memory" or elasticity than pure rubber seals.

Applications and Usage

Our Hammer Union Seals are essential for any high-pressure fluid transfer system in the oilfield, including:
Hydraulic Fracturing (Fracking)
Well Cementing and Acidizing
Manifold and Pipeline Connections
Mud Pumps and Blowout Preventers (BOP)
Water Flood Lines
Sour Gas (H2S) Service (when using HNBR or FKM materials)
