The BRASS CRAFT SERVICE PARTS 337-733 is a chromed plastic shower flow control fitting designed to regulate water flow in residential shower supply lines. It connects using 1/2 inch Female Pipe Thread on the inlet side and 1/2 inch Male Pipe Thread on the outlet side, making it a straightforward inline installation. The chromed finish blends with standard shower trim hardware. This fitting is installed by licensed plumbers or qualified service technicians performing flow control upgrades or fixture replacements.
This flow control is suited for residential shower applications where water flow regulation is required at the supply connection point. It fits into standard 1/2 inch threaded pipe systems commonly found in residential bathroom plumbing. The FPT x MPT configuration allows direct inline installation without additional adapters in most standard shower riser or drop-ell setups. It is packaged in quantities of five units per pack, making it practical for service vans and small stocking orders.
Designed as an OEM-style replacement or service fitting for residential shower plumbing systems using standard 1/2 inch threaded pipe connections.
Installation is performed by a licensed plumber or qualified technician. Shut off the water supply and relieve line pressure before beginning work. Use thread seal tape or pipe joint compound on all threaded connections per standard plumbing practice and local IPC requirements. Do not overtighten plastic-bodied fittings, as excess torque can crack the body.
