FAQs

Can I use Carbon Steel QRCs in water lines?

Not recommended unless plated. Use SS 304/316 for water.

What is the corrosion resistance like?

Plated CS QRCs resist moderate corrosion, but not as much as stainless steel.

Are these QRCs suitable for high-pressure hydraulics?

Yes. Carbon steel performs excellently under high pressure (up to 10,000 PSI).

Can I request carbon steel QRCs with special coatings?

Yes. We offer zinc, phosphate, and nickel-plated finishes.

Are your CS couplings interchangeable with ISO-standard equipment?

Yes. They’re compatible with Parker, Stucchi, Holmbury-type ISO A/B designs.
