    Most Frequently Asked Questions

    other products?"Do you sell stainless flare, compression fittings or stainless tubing?"
    nopeWe also offer stainless water flexes, stainless gas flexes, and stainless hose clamps. But what we show above is all that we sell in the way of stainless fittings, and we don't sell tubing. We do sell brass flare and compression fittings.

    We hope that we have helped you on this page with stainless steel fittings,
    and thank you for helping make PlumbingSupply.com the most famous Internet plumbing supplier.
