In the oil and gas industry, ensuring leak-free connections in high-pressure and harsh environments is critical. Weco Hammer Union Seals are designed to provide reliable one-way, high-pressure, and static sealing for a wide range of applications. These seals are widely used in static and low-speed sealing scenarios, offering excellent performance even in challenging conditions such as light gas, refrigerant, vacuum environments, and surfaces with poor finish.

Applications of Hammer Union Seals

Hammer union seals are essential components in preventing leaks in hammer union pipe connections. They are commonly used in industries such as:

Chemical Processing

Offshore Drilling

Petrochemical

Water and Gas industries.

These seals are particularly valued for their ability to maintain sealing integrity under high pressure and in demanding operating conditions.

JST offers two distinct lines of hammer union seals to meet diverse industrial requirements:

1. Elastomer Seals

Made from high-quality elastomers, these seals are ideal for standard pressure applications.

They provide excellent sealing performance for static and low-speed conditions.

2. Elastomer Seals with Anti-Extrusion Rings

Reinforced with brass or stainless steel anti-extrusion rings, these seals are designed for high-pressure applications.

The anti-extrusion ring prevents the elastomer from deforming under extreme pressure, ensuring long-term reliability.

Materials

JST's hammer union seals are available in a variety of configurations and materials to suit specific operational needs. Key material options include:

NBR (Nitrile Rubber)

HNBR (Hydrogenated Nitrile Rubber)

Viton (FKM)

For cold weather applications we offer both a low temperature rated (-50°C to +120°C) NBR and HNBR elastomers.

Features

High-Pressure Resistance: Designed to withstand extreme pressure conditions, ensuring leak-free performance.

Versatile Material Options: Choose from NBR, HNBR, or Viton to match specific chemical and temperature requirements.

Anti-Extrusion Reinforcement: Brass or stainless steel rings enhance durability in high-pressure environments.

Wide Temperature Range: Suitable for both high-temperature and low-temperature applications.

Excellent Surface Adaptability: Effective even on surfaces with poor finish, ensuring a reliable seal.
