Brass Tube Fittings Feature Box

Brass tube fittings can be made for chrome plating treatment

You can choose single or double ferrules for brass tube fittings

You can print your logo on the brass tube fittings

Brass tube fittings can be used in several industries.
Brass Tube Fittings Chrome Plating Treatment
Normally, the brass tube fittings’ color is bright yellow, which can be distinguished from other material fittings. The bright yellow is the original color of brass material.
NPTLOK can offer the chrome plating treatment on the surface of fittings, which looks like a stainless steel color. The most important is that chrome plating treatment can increase the durability and strength of the surface, which reduces the chance of rust and strengthens the metal.
Chrome plating treatment can be easily applied to any kind of metallic surface, for example, stainless steel, aluminum, and copper materials. It is especially suitable for the marine environment.
If your project is related to the marine environment, we will do the chrome plating treatment on the fittings.


Brass Tube Fittings Single or Double Ferrules
As we all know ferrules are the core of the tube fittings. NPTLOK can offer you brass single ferrule and double ferrule tube fittings according to your project requirements.
Single ferrule means one ferrule that helps metal-metal sealing connections, which has few leakage. It is easier to assemble because there is one ferrule. Plus they can provide better resistance to fluctuations in cycling temperature and high vibrations.
Brass single ferrule size is available in 1/8”-1”, and it is made hardened treatment for standing higher pressure. The pressure is from 3000psi to 10000psi according to different sizes.
Double ferrules include front ferrule and back ferrule which better perform in sealing connections. They are also made hardened treatment to stand higher pressure, which is from 3000psi to 10000psi based on sizes from 1/8”-1”.
If you require higher pressure, contact us for more details.
