Discover the Superior Seal of Vintage-Quality Brass Fittings
Return to an era of uncompromising quality with this New Old Stock (NOS) brass connector. Sourced for the Vintage Parts Revival collection, this fitting represents the pinnacle of durable, precision manufacturing. Made from solid, corrosion-resistant brass, this adapter is brand new and ready to provide a dependable, leak-free connection for your critical fluid and air lines.
This machined adapter joins 5/8" OD tubing to a 1/2" NPTF female port. The compression-style end creates a powerful, solder-free seal on hard metal tubing (like copper, aluminum, or brass) by simply tightening the nut, making it ideal for both new installations and on-the-fly repairs. The male end features NPTF (National Pipe Taper Fuel) threads, also known as Dryseal threads, which are engineered to create a seal without the need for thread sealant.
For anyone restoring classic machinery or building systems that demand absolute reliability, this NOS brass fitting is the perfect choice, offering quality that has truly stood the test of time.
Features & Benefits:
Solder-Free Connection: The compression fitting allows for a secure, mechanical seal on 5/8" OD tubing without heat or soldering.
