Descrição de produto


Product Overview

This Brass Lead Free Internal Half Threaded Socket Fitting is a plumbing component designed to connect pipes in water, natural gas, LPG, and low-pressure oil systems. The term “half threaded” means that the internal bore is partially threaded (typically 50-70% of the total socket depth), while the remaining portion is smooth.

Manufactured by Hongxin Pipe Fitting, this socket fitting uses certified lead-free brass (ASTM C46400 or CW509L equivalent), with lead content below 0.25% by weight, complying with:

  • NSF/ANSI 61 – Drinking water system components

  • RoHS Directive (2011/65/EU) – Restriction of hazardous substances

  • California AB1953 and Vermont S152 – Lead-free plumbing laws
