Bronze Press-Fit Elbow Adapter

This Viega 79545 fitting joins a one inch press-fit copper tube to a half inch female NPT thread in a ninety degree turn. The bronze body and EPDM O-ring suit potable water systems. It meets ASTM B75 and ASTM B88 standards for material quality.

Rated for two hundred psi

Under sustained pressure and temperature the bronze construction and EPDM seal maintain integrity without degradation. The press-fit connection on the copper side creates a permanent mechanical joint that does not rely on solder or thread sealant. The female NPT side accepts standard pipe threads for reliable transitions.

One inch press-fit to half inch FNPT in a ninety

This specific size combination and connection type determine whether the fitting matches the piping layout. Builders needing a different tube size, thread size or straight coupling cannot use this part. The fixed ninety degree angle also prevents use where an adjustable or forty five degree bend is required.

Questions about this item

Does the bronze elbow generate noise or heat when water runs continuously at 200 psi?

The bronze press-fit elbow is a passive fitting with no moving parts, so it produces no noise or heat of its own during continuous flow.

What existing pipe and tools must I already have to install this 1 in press-fit by 1/2 in FNPT elbow?

You need 1 in copper tubing sized to ASTM B88, a compatible press tool and jaws, plus 1/2 in NPT male threads on the mating pipe or valve.

Will this 90 degree adapter seal reliably against older copper pipe that meets ASTM B75?

Yes, the EPDM O-ring and press-fit design are engineered for copper tube complying with ASTM B75 and B88, creating a 200 psi seal.
