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
| Parameter | Value / Range |

| Working pressure – gas (natural/LPG) | 300 PSI (20.7 bar) at 23°C |
| Working pressure – oil (low pressure) | 250 PSI (17.2 bar) at 23°C |
| Temperature range | -20°C to +120°C (-4°F to +248°F) |
| Thread length (threaded portion) | 40-60% of total socket depth (size dependent) |
