Asc Engineered Solutions EXD.NB Hex Head Pipe Bushing 3/4x1/2

Product Description

The ASC ENGINEERED SOLUTIONS EXD.NB is a galvanized malleable iron hex head pipe bushing rated at 150 lb, sized 3/4 x 1/2 inch nominal with a male NPT (MNPT) external thread and female NPT (FNPT) internal thread. It is used to reduce a larger threaded pipe opening to a smaller pipe thread size. The hexagonal head allows wrench engagement for secure installation without slipping. Galvanized finish provides corrosion resistance for use in wet, damp, or mildly corrosive environments. Plumbers, pipefitters, and HVAC installers typically install this fitting in gas, water, and general-purpose pipe assemblies.

This bushing is suited for residential and light commercial plumbing, gas piping, and HVAC condensate or supply line applications. The 3/4 inch MNPT outer thread connects to a 3/4 inch female-threaded fitting or valve, while the 1/2 inch FNPT inner thread accepts a 1/2 inch male-threaded pipe or fitting. Domestically manufactured to standard 150 lb malleable iron fitting dimensions.

Key Features

• 3/4 x 1/2 inch nominal size reduces pipe thread from 3/4 inch to 1/2 inch
• MNPT x FNPT end style for standard threaded pipe connections
• 150 lb pressure class malleable iron construction
• Galvanized finish for corrosion resistance in wet and damp environments
• Hex head design allows wrench tightening for a secure, leak-free connection
• Domestically manufactured to standard malleable iron fitting dimensions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 150 lb malleable iron threaded pipe systems using 3/4 inch and 1/2 inch NPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service application. Apply thread sealant or PTFE tape to the male threads before assembly. Hand-tighten first, then wrench-tighten to avoid cross-threading or over-stressing the fitting. Shut off and depressurize the pipe system completely before removing any existing fitting or making new connections.
