Midland Industries 23300X16 Brass Pipe Coupling 1 in Nptf

Product Description

The MIDLAND INDUSTRIES 23300X16 is a straight pipe coupling following the SAE pattern, connecting two 1-inch female NPTF ports in brass construction. Rated to 1000 psi, it is built for use in pressurized plumbing and fluid-handling systems where a reliable, leak-resistant thread engagement is required. The NPTF thread form creates a pressure-tight seal through thread interference alone, reducing reliance on sealant tape or compound. At 1.89 inches in length with a 1-1/2 inch hex, this coupling installs quickly with standard wrenching access. Plumbers, pipefitters, and mechanical contractors install this type of fitting in both new construction and retrofit applications.

This coupling is suited for residential and commercial plumbing, HVAC hydronic piping, compressed air lines, and general fluid distribution systems. The brass body is compatible with brass, bronze, copper, steel, aluminum, and iron pipe, making it a versatile choice across mixed-material installations. The 1-11-1/2 thread pitch matches standard 1-inch NPT and NPTF pipe. It performs reliably across a wide service temperature range, rated from -65 to 250 degrees F.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters using a standard pipe wrench or adjustable wrench on the 1-1/2 inch hex flats. Shut off system pressure and depressurize the line completely before removing or installing any pipe fitting. NPTF threads are designed to seal through thread-form interference, but applying a compatible thread sealant compound is common practice for additional assurance. Installation should comply with applicable local plumbing codes and the International Plumbing Code (IPC) where adopted.
