Hammer Unions
Hammer Unions & Hose Union Fittings – TYA

TYA offers a complete range of OFC/OFE hammer unions designed for durability, reliability, and high performance in demanding applications. Available in sizes up to 15,000 psi working pressure, our hammer unions are offered in pressure seal, non-pressure seal, and welded styles to suit diverse operational needs.

All OFE hammer unions deliver pressure-tight, positive sealing and are available in both standard service and sour gas models. For sour gas applications, our hammer unions undergo special heat treatment for controlled hardness and incorporate fluorocarbon elastomer seal rings for superior sealing performance and enhanced safety.

Specifications for Threaded & Butt Weld Hammer Unions ensure compatibility, strength, and longevity in critical environments.

Our OFC/OFE Figure 206 Hose Union Fittings, crafted from high-quality cast ductile iron, provide a versatile solution for hose connections. Also known as Hose Barb Unions, they feature a union end connection compatible with Figure 200/206 and include an integral hose shank on both male and female subs.

The Figure 206 design eliminates the need for welding a hose nipple onto a hammer union, offering significant time and cost savings. Each unit is tested to twice the rated working pressure, meeting the rigorous demands of TYA’s high-performance hose applications.

Key Advantages:

High-pressure capacity up to 15,000 psi

Available in multiple connection types and sizes

Specially treated for sour gas service durability

Precision engineering for positive, leak-free sealing

Time-saving, weld-free hose connection design

Exceeds standard pressure testing requirements

TYA’s hammer unions and hose fittings are engineered to deliver maximum safety, reliability, and efficiency in oilfield, industrial, and heavy-duty operations.
Integral Union Connections
Integral Union Connections & Accessories – TYA

At TYA, we supply high-pressure integral union connections (OFC/OFE) engineered for exceptional durability and performance. Available in 2" and 3" sizes with pressure ratings up to 15,000 psi NSCWP (Non-Shock Cold Working Pressure), our high-strength alloy steel unions feature a lightweight design for easier handling without compromising safety. Each integral union connection undergoes a controlled heat-treat process for maximum strength and reliability in oilfield and industrial applications.

Union Changeover & Crossover Adaptors
TYA offers union changeover adaptors and union crossover adaptors in female-to-male, female-to-female, and male-to-male configurations from 1″ to 4″. Designed for standard service up to 15,000 psi and sour gas service up to 10,000 psi, these high-pressure adaptors ensure secure, leak-free, and compatible connections across multiple thread types.

Union Bull, Gauge & Lifting Bull Plugs
Our union bull plugs, gauge plugs, and lifting bull plugs are available in multiple sizes and thread types, delivering pressure ratings up to 15,000 psi NSCWP for standard service and 10,000 psi for sour gas service. Built from premium alloy steel, these plugs provide dependable sealing and long-term durability in harsh environments.

Union Male & Female to Pipe & Tubing Thread Swages
TYA’s union-to-pipe thread swages and union-to-tubing thread swages come in 1″ to 4″ sizes, with pressure ratings from 6,000 psi to 10,000 psi. Engineered for high-pressure connections, these swages deliver secure, leak-proof performance in oilfield, industrial, and heavy-duty applications.
Plug Catchers
TYA plug catchers and components in all various sizes and pressure ratings. Custom manufacturing is available.

Bestway plug catchers support well cleanup by filtering isolation plug remnants and fragments of casing, cement, and loose rock from the perforation area. Catchers feature a single barrel with bypass or dual barrels (for continuous filtration during blowdown activities). Our 10,000-psi to 15,000-psi working pressure catchers remove large solid debris immediately after the fracturing stack.
