Hex Bushing 304

Threaded Reducers and Bushings for Pipe-Size Transitions

Hex Bushing 304 provide threaded stainless-steel connections for industrial water, compressed air, process and utility piping. Threaded fittings are widely used for smaller-diameter piping where a compact mechanical connection is practical.

Match NPT, BSPT or BSPP thread forms correctly; they are not automatically interchangeable. Sealing method, pressure, temperature, stainless grade and media compatibility should all be confirmed for the exact fitting.

Key Benefits

  • Compact mechanical pipe connections
  • Wide range of elbows, tees, couplings, nipples and reducers
  • Available in common industrial thread standards
  • Suitable for maintenance and OEM piping
  • Stainless construction for corrosion resistance

Common Applications

  • Compressed-air piping
  • Industrial water systems
  • Chemical and process equipment
  • Food and beverage utility lines
  • Fire-protection and cooling systems
  • OEM machinery

Frequently Asked Questions

What are threaded stainless fittings used for?

They connect pipe, hose adapters and equipment ports in industrial fluid and compressed-air systems.

What is the difference between NPT and BSP threads?

NPT uses a different thread form from BSP. BSPP is parallel and BSPT is tapered, so matching the correct thread is important.

How does BSPP seal?

BSPP is a parallel thread and normally relies on a gasket, bonded seal or other face/shoulder sealing method rather than thread taper alone.

How do tapered threads seal?

NPT and BSPT rely on taper plus an appropriate thread-sealing method where specified.

Why choose stainless steel?

It provides corrosion resistance and durability for many industrial environments.

Can threaded fittings be used for compressed air?

Yes, when the fitting pressure rating, thread and sealing method are suitable.

How do I select 304 versus 316 stainless?

316 generally offers better resistance to chlorides and many corrosive media; verify the application requirements.

What should I check before ordering?

Confirm thread standard, size, stainless grade, pressure, temperature and media.
