Polished 316 stainless steel reducing bushing, threaded, 1 27/32 in overall length

CALBRITE

CALBRITE Reducing Bushing 316 SS 1/2 to 1-1/2 in

SKU CH-97S1-DAEXN

A 316 stainless steel reducing bushing connects 1/2 inch conduit to 1-1/2 inch trade sizes with NPS and NPT threads

  • Product typeConduit & Raceways
  • 316 stainless steel resists corrosion in harsh environments
  • Reduces conduit from 1-1/2 in to 1/2 in trade size
  • Polished finish protects against surface oxidation
  • Threaded NPS and NPT connection ensures secure fit
  • Lightweight at .6 lb for easy installation

Conduit Reducer 1/2 to 1-1/2 in

This 316 stainless steel reducing bushing connects smaller conduit to larger trade sizes. It fits RMC and IMC conduit types with NPS and NPT threaded connections. The polished finish resists corrosion in demanding environments. Overall length measures 1 27/32 in and weight is 0.6 lb.

Suited for Stainless Conduit Systems

Installers joining 1/2 in conduit to 1-1/2 in fittings in rigid or intermediate metal raceways will find the correct thread engagement. It is not for non-threaded conduit, plastic raceways, or metric-sized systems. Buyers needing a different reduction ratio or non-stainless material should look elsewhere.

Sustained Load in Corrosive Settings

The 316 stainless construction maintains thread integrity and sealing under continuous vibration and chemical exposure. Polished surfaces reduce deposit buildup during long service periods. Threaded NPS and NPT joints stay secure without loosening over time. Weight of 0.6 lb adds minimal stress to support structures.

Questions about this item

What conduit sizes must I already have to connect with the 1 1/2 in to 1/2 in reducing bushing?

You need rigid metal conduit or intermediate metal conduit in both the 1 1/2 in trade size and the 1/2 in trade size, because the bushing threads are NPS and NPT for those exact conduit types.

Will the 316 stainless steel bushing corrode when joined to older galvanised rigid conduit?

The 316 stainless steel material resists corrosion, but direct contact with dissimilar metals in damp conditions can still create galvanic action, so inspect joints periodically.

How do I confirm the bushing is seated correctly after threading it onto the conduit?

The overall length is 1 27/32 in and overall height is 1 in; when hand-tight plus one to two wrench turns the faces should be flush with no visible thread gaps.
