1-1/4 inch x 1 inch Stainless Steel Hex Head Bushing Male x Female

1-1/4 Inch x 1 Inch Stainless Steel Hex Head Bushing – Male x Female NPT

The 1-1/4 inch x 1 inch stainless steel hex head bushing is a corrosion-resistant fitting used to reduce threaded openings in stainless steel piping systems. It features a male NPT thread on the larger end and a female NPT thread on the smaller end, with a hex head for wrench tightening during installation. This component is commonly used in systems requiring strength, pressure resistance, and long-term material integrity.

Material and Performance Attributes

Manufactured from 304 or 316 stainless steel (depending on system specification), this reducing bushing supports use in potable water, chemical, compressed air, and industrial fluid handling systems. Its robust design and dimensional accuracy allow for a secure, leak-resistant fit when properly installed:

• ✅ Corrosion-Resistant Alloy – Suitable for harsh or corrosive environments, including coastal, chemical, and high-humidity applications.
• ✅ Hexagonal Head Design – Allows for tool-assisted torque and straightforward installation in confined areas.
• ✅ Threaded Reduction – Reduces a 1-1/4 inch female NPT opening to accept 1 inch male NPT pipe or fitting.
• ✅ Machined Threads – NPT threads are manufactured to ANSI B1.20.1 tolerances for consistent sealing with compatible components.

Installation Guidelines

Apply an appropriate thread sealant or PTFE tape approved for the system media. Tighten with a wrench using the hex head—avoid over-torqueing to prevent thread damage or cracking of mating components. Not intended for welding or press-fit systems. Always verify pressure and temperature ratings according to application requirements.

Common Applications

This stainless steel bushing is typically found in mechanical rooms, processing lines, and potable water systems where reductions in piping size are necessary. Common uses include adapting pump ports, valves, manifolds, or outlet fittings in commercial, industrial, and institutional environments.

Technical Specification Summary

• Material: 304 or 316 Stainless Steel
• Connection: Male NPT x Female NPT
• Size Reduction: 1-1/4 inch to 1 inch nominal pipe size
