NPTLOK Bulkhead Union
NPTLOK has been a manufacturer of bulkhead unions for more than 20 years with mature technology and competitive price.
A Bulkhead union is used to connect tubes and have a straight design with connectors on ends. A bulkhead union contains two locknuts to compress the tube and create a high-pressure seal. Determining the diameter of bulkhead unions is very important because bulkhead unions are used as distribution outlets in the piping systems.
The quality and strength of material for making bulkhead unions are also very important. The use of materials depends on customers’ project requirements.

Good Quality Ferrules of Bulkhead Union
Ferrules are important for bulkhead unions, which have the strength to resist high pressure and to protect from leaking out.
We have imported equipment to produce ferrules, and the ferrules will be made with hardened treatment to strengthen the hardness.
Because of the good quality ferrules, the pressure of 1/4” bulkhead union can reach 100Mpa. You can get samples of bulkhead unions to test ferrule quality.

Swagelok has a notice that ”
Over the years, we’ve become aware of many manufacturers with products which claim to be interchangeable and intermixable with the Swagelok Tube Fitting.
We do not believe that any manufacturer can reliably, repeatedly, and uniformly replicate the products of another manufacturer. For this reason, we believe that interchanging and intermixing component parts made by different manufacturers can result in unpredictable performance and increased costs. We believe also that this is an unsound practice and can be dangerous in critical applications.
