Signature stainless steel

Stainless steel is inert to practically all commercial chemicals, acids, alcohols, coolants, elastomers, petroleum compounds, solvents vinyl’s, synthetic lubricants and hydraulic fluids. It is also impervious to atmospheric conditions. It will therefore not rust or deteriorate over time even in challenging environments and most importantly will not break down and contaminate the application material, fluid or gas.

Stainless steel 316 has been approved by the FDA and other governmental organizations for use in food handling and pharmaceutical applications. Stainless steel 316 is more resistant than 304 to salt (which is found in most foods). It is easy to clean and sterilize which makes it the perfect material for these applications.

Stainless Steel 316L is the standard material for our adapters and hose couplings. We can also provide our flexible metal hose assemblies with SS316 braid and hose. We have selected this material because of its combined chemical and mechanical properties that make it the best material for your specialized applications.


Tube adapters

Our stainless steel tube fittings are more commonly called JICs. Our SAE J514 parallel threaded tube adapters (37° flare seating surface) are, in many cases, better suited for higher pressure fitting applications. We offer JICs in stainless steel caps, plugs elbows, tees, crosses, straights, and bulkhead adapters.

O-Ring adapters

O-ring adapters, also known as ORB or SAE adapters, have parallel threads which seal with the o-ring on the chamfer of the mating part. We offer our ORB fittings in stainless steel 316L in straight, elbows, plugs, adjustables, tees, as well as converting to other threads (such as JIC or NPT) on the second end.

Pipe adapters

We offer SS316 NPT adapters in straight, elbows, caps, plugs, unions, bushings, expanders and reducers. We also offer NPSM ends with a 30° cone which seats on the 30° chamfer on our male NPT end. Unlike the stainless steel tube fittings, the NPT adapters seal on the tapered threads (and in some applications, with thread lubricant of some type).
