Holyoke Fittings 113-630 Brass Nipple 3/8 X 3 Inches

Product Description

The HOLYOKE FITTINGS 113-630 is a brass pipe nipple measuring 3/8 inches in diameter and 3 inches in length. Nipples are short threaded pipe sections used to connect two female-threaded fittings or to extend a pipe run. This fitting is machined from brass, making it well suited for water, gas, and fuel-oil service in plumbing, HVAC, and light industrial applications. Licensed plumbers and pipefitters install this type of fitting in both residential and light commercial systems where a corrosion-resistant, threaded connection is required.

This nipple is a standard close-to-short-length fitting appropriate for tight-clearance installations. It is used in supply lines, manifold assemblies, boiler piping, gas-appliance connections, and similar applications where a compact threaded section is needed. The 3/8-inch pipe size is common in residential water distribution, gas-valve inlets, and small-bore instrument connections. Sold in a box quantity of 10, this fitting is practical for service truck stock or job-site use.

Installation Notes

Install and service threaded brass fittings in accordance with applicable plumbing and mechanical codes, including IPC and IFGC requirements for the specific service type. Shut off and depressurize the supply line before installation or removal. Apply thread sealant or PTFE tape appropriate for the service medium before making up the joint.
