Hammer Union
Hammer unions are the most versatile connections in the oil and gas industry, widely recognized for their ability to quickly connect pipe sections without requiring the use of special tools. Due to this ease of use, combined with their unmatched sealing property, they are ideal for applications where reliability is a factor.
A Hammer Union consists of three main components, the wing nut, male union and a female union. These three components when joined creates a strong seal connection. Asian Sealing Products specializes in manufacturing Hammer Unions using forged/ Cast raw materials customized to meet your specific service needs. Our Hammer Union lineup includes sizes ranging from 1 to 12 inches, with ratings up to 20,000 PSI of cold working pressure. Additionally, we prioritize quality in producing unions tailored for sour gas service, adhering strictly to standards such as API RP-14E & NACE MR-01-75. ASP-branded Hammer Unions are suitable for replacement with those from WECO or other brands.

Answers to all your possible questions.
What are the main advantages of Hammer unions?
The main advantage of hammer unions is their ability to do rapid connection and disconnection without needing the usage of special tools. Apart from that the hammer unions provide excellent mechanical and sealing properties enabling them for high critical applications.
What Materials are hammer unions typically made of?
Hammer unions are generally made with Carbon steel, alloy materials and stainless steel. This allows them to withstand enormous pressures and handle the corrosive environments better. The selection of Hammer union material will be dependant on the type of application and the pressure that the union will be subjected to.
What are the different types of Sealing design?
Low-pressure hammer unions have a metal-to-metal type of sealing, which is created due to the conical and spherical surfaces of male and female union. Hammer unions that are used in medium-pressure applications will generally have an “O” Ring used in addition to the existing meal-to-meal seal. Hammer unions intended for High-pressure applications will have a lip-type seal ring which will be placed in the female union.
How do you maintain Hammer unions?
Always ensure that the sealing surfaces and elements of the hammer unions are in good form. General maintenance involves inspecting signs of damage, corrosion, and wear. Ensure to keep the thread area clean from rust and other debris.
