Collection: STEEL COMPRESSION UNIONS

we have here, new steel compression unions, these are designed to work with steel tubes in hydraulic applications. should be used on steel tubing as these will crush Nickle, brass and aluminum tubing. these will handle more than 5,000 psi. WARNING; no compression fittings, steel, brass or otherwise should be used in repair of automotive brake lines. compression sealing is only as good as the sealing tube properties; brake line tubing is thin walled and compression unions will crush the tubing in time. brake tubing collapses from the inside out, so what may look good, the quick fix may not last long at all. these come in 1/8, 3/16, 1/4, 5/16, 3/8 and 1/2 sizes. sold (1) each
