The ASHLAND WATER GROUP MAR100NL is a 1-inch brass male adapter designed for connecting plastic pipe in residential and commercial plumbing systems. The fitting features a rope loop barbed end that grips plastic pipe securely, eliminating the need for additional clamps in low-pressure applications. Constructed from lead-free brass, this adapter complies with current lead-free plumbing laws, making it suitable for potable water installations. Plumbers and pipefitters install this fitting when transitioning between threaded metal connections and flexible or rigid plastic pipe runs.
This adapter is used in residential water supply lines, irrigation systems, and light commercial plumbing where a threaded male connection must interface with plastic pipe. The barbed end provides a friction-fit connection that is straightforward to install in tight spaces. Sold in packages of six, it is a practical stocking item for service trucks and supply rooms handling recurring fitting replacements or new plumbing rough-ins.
Designed as an OEM-style replacement or new-installation fitting for 1-inch plastic pipe systems requiring a male threaded transition in potable water or irrigation plumbing applications.
Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) requirements for the jurisdiction. Shut off and depressurize the water supply line before disassembling any existing fittings. Apply appropriate thread sealant or PTFE tape to the male threads before making the threaded connection. Do not overtighten the threaded joint, as brass fittings can crack under excessive torque.
