Asc Engineered Solutions 8700149050 Galvanized Close Nipple

Product Description

The ASC Engineered Solutions 8700149050 is a 1/2-inch close nipple machined from welded steel and finished with a hot-dipped galvanized coating. Close nipples are threaded end-to-end with no unthreaded center section, making them the right choice when two fittings or valves must be joined with minimal standoff. This nipple meets ASTM A53 standards and is manufactured to Schedule 40 wall thickness. Lead content on wetted surfaces is controlled to no more than 0.25 percent weighted average, keeping it compliant for potable water and general plumbing use. Plumbers and pipefitters install this type of nipple in water distribution, gas distribution, and general mechanical piping systems.

This close nipple is suited for residential and light commercial piping applications where a short, rigid connection is needed between threaded components. Typical uses include connecting valves, unions, elbows, and tees in water supply lines, steam systems, and low-pressure gas piping. The galvanized finish provides corrosion resistance for both indoor and exposed applications where moisture is a factor.

Key Features

• Hot-dipped galvanized finish for corrosion resistance in wet and exposed environments
• Schedule 40 wall thickness for standard-pressure piping applications
• Meets ASTM A53 specification for welded steel pipe
• Lead content limited to 0.25 percent or less on wetted surfaces for potable water compliance
• Close configuration — threaded end-to-end with no bare center for tight-clearance connections
• 1/2-inch nominal pipe size with standard NPT threading

Compatibility

Designed as an OEM-style replacement or standard component for 1/2-inch NPT threaded piping systems using Schedule 40 steel pipe fittings in plumbing, HVAC, and mechanical piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the system type. Apply a listed pipe thread sealant or PTFE tape to the male threads before assembly, and tighten with a pipe wrench to proper thread engagement — avoid over-tightening, which can crack fittings or distort threads. Shut off and depressurize the line completely before removing any existing nipple or fitting. For gas service, verify all joints with an approved leak-detection solution after pressurizing the system.
