Reducer Bushing 1-1/4 to 1 in NPT

The Zoro Select 400B113N114010 is a 304 stainless steel hex bushing that reduces a 1-1/4 inch male NPT thread to a 1 inch female NPT opening. It is built for Class 150 service and meets ASTM A351 and MSS SP-114 standards. The corrosion-resistant construction handles air, natural gas, oil, steam, and potable or non-potable water.

Installers needing Schedule 40 Class 150 fittings

This bushing suits plumbers and maintenance crews joining Schedule 40 pipe where a hex profile allows wrench tightening. The 45.5 mm across-flats dimension and 33 mm overall length fit standard tooling. Buyers requiring higher pressure ratings, different thread forms, or integral sealant must select another fitting.

300 psi general pressure rating

The fitting carries a maximum operating pressure of 300 psi for general service and 150 psi for steam. This pressure ceiling is the primary specification that determines whether the part matches the system design. Verify the application pressure before installation.

Questions about this item

Does this bushing require any specific pipe schedule on the mating fittings?

It is compatible with Schedule 40 piping, so the connecting male and female threads should match that schedule for proper engagement.

Will the 45.5 mm hex flats clear a standard adjustable wrench when installed next to older iron pipe?

The 45.5 mm across-flats dimension fits common 1-3/4 inch wrench openings, allowing clearance alongside existing iron NPT connections.

After threading the 1-1/4 inch male end into a female port, how can I confirm the joint is sealed to the 300 psi rating?

Pressurise the system with air or water up to the rated 300 psi and inspect the joint for leaks; no sealant is pre-applied, so proper thread compound or tape must be used during assembly.
