Holyoke Fittings 113-820 Brass Nipple 0.5x2 in

Product Description

The HOLYOKE FITTINGS 113-820 is a brass pipe nipple used to connect or extend threaded pipe runs in plumbing, HVAC, and light industrial piping systems. Measuring 0.5 inches in diameter and 2 inches in length, this close-tolerance fitting installs between threaded fittings, valves, or equipment ports wherever a short rigid section of pipe is needed. Brass construction provides corrosion resistance and reliable thread engagement on standard NPT connections. Plumbers and pipefitters reach for nipples like this on water supply, gas, and hydronic heating lines as part of routine rough-in and service work.

This nipple is suited for residential and light commercial applications including water supply risers, boiler piping, gas appliance connections, and pump headers. The 0.5-inch diameter fits the most common pipe size found in residential plumbing systems. Sold in a box quantity of 10, it is a practical stocking item for service vans and shop inventory.

Key Features

• Brass construction for corrosion resistance and durability in wet and gas service environments
• 0.5-inch nominal diameter fits the most widely used residential and light commercial pipe size
• 2-inch length suitable for close-quarters connections and extension of threaded runs
• Standard NPT threading for compatibility with common fittings, valves, and equipment

Compatibility

Designed as a standard NPT-threaded replacement or new-installation nipple for 0.5-inch pipe systems in plumbing, hydronic heating, and gas piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service type. Shut off the water or gas supply and relieve system pressure before disassembling any threaded connection. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not over-tighten brass fittings, as the material is softer than steel and threads can be damaged by excessive torque.
