B K Mueller 587-050HC Black Steel Pipe Nipple 1.5x5 in

Product Description

The B K Mueller Industries 587-050HC is a black steel pipe nipple used to connect sections of pipe in low-pressure gas, air, and fluid distribution systems. Sized at 1.5 inches in diameter and 5 inches in length, this close-cut nipple threads directly into fittings, valves, and manifolds using standard NPT threads. It is a standard consumable in plumbing and mechanical rough-in work, installed by licensed plumbers and pipefitters during new construction and retrofit projects. Sold in a package quantity of five, this nipple is suited for applications requiring multiple connections in a single service call.

Black steel pipe nipples of this type are widely used in residential and light commercial gas piping, compressed air lines, and industrial fluid systems where galvanized or plastic fittings are not specified. The 1.5-inch diameter makes this nipple a common choice for branch lines and appliance drops in natural gas and propane distribution systems. Plumbers and gas fitters routinely stock nipples in multiple lengths to handle varied rough-in measurements in the field.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off gas or fluid supply and depressurize the line before threading or replacing any nipple. Apply an appropriate thread sealant or pipe-thread compound rated for the service medium before making up joints. Do not over-thread or force connections, as this can damage fitting threads and compromise the seal.
