The PLUMB SHOP DIV BRASSCRAFT 861-237 is a plastic shower flow diverter with a chrome finish, designed to split or redirect water flow between a fixed shower head and a handheld shower unit. The fitting connects using a 1/2 inch female pipe thread (FPT) inlet with two 1/2 inch male pipe thread (MPT) outlets, allowing a plumber or experienced installer to tee off an existing shower arm without cutting into the wall supply. The chrome-finished plastic body keeps the unit lightweight at approximately 0.1 pounds while blending with standard shower trim. This is a carded retail-format part suited for service calls, repair jobs, and fixture upgrades in residential bathrooms.
This diverter is used in residential shower applications where the homeowner or end user wants to add a handheld shower to an existing fixed shower head setup. The 1/2 inch pipe thread connections are standard for shower arm fittings, making this a common drop-in addition during fixture upgrades or bathroom remodels. A plumber or plumbing technician typically handles the installation, though the straightforward threaded connections also make it accessible for knowledgeable DIYers. No soldering or specialty tools are required beyond pipe wrenches and thread sealant.
Designed as an OEM-style replacement and add-on fitting for residential shower systems using standard 1/2 inch pipe thread shower arm connections.
Installation is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply to the shower and relieve line pressure before removing the existing shower arm fitting. Apply PTFE thread tape or an approved pipe thread sealant to all male threads before assembly. Hand-tighten connections first, then snug with a pipe wrench — do not overtighten plastic fittings, as excess torque can crack the body.
