Our stainless steel 91 series crimp fittings are suitable for SAE 100R14 PTFE Hoses.
Yes, our stainless steel 91 series crimp fittings are designed to compatible with Parker 91 series.
Our standard is dual SS 316/316L that conforms to both the 316 and 316L specifications.

SS 316 is known for its outstanding corrosion resistance and strength.

SS 316L is the low-carbon content of SS 316. The reduced carbon content minimizes the risk of carbide precipitation during welding, making it ideal for welded structures.

Yes, we do. When we develop a new hose fitting, we first make some hose assemblies to do impulse test before releasing to market.

However, we don’t do impulse test for every batch.

Of course, we could do impulse test if a customer has a request.

Sure, we accept OEM orders. We can laser mark your logo and part number on the fittings according to your specific requirements.
No, at present, we are focused on stainless steel fittings only. Because all our CNC lathe machines and equipment are designed for manufacturing stainless steel fittings.
Main materials include SS 304(1.4301), SS 316L(1.4404) & SS 316Ti(1.4571)
