Value Brand Pipe Nipple Schedule 40 1/2 in Close

SKU CH-CJZS-SHTY3

A Schedule 40 steel pipe nipple with 1/2 in NPT male threads on both ends, rated 300 psi at 150 °F for air, gases, oils and non-potable water

  • Schedule 40 steel rated for 300 psi at 150 °F
  • Close 1/2 in NPT male threads for tight-space plumbing
  • Seamless ERW construction handles air, gases, oils and non-potable water
  • Black-coated Grade B steel resists corrosion in industrial environments
  • California Proposition 65 warning for cancer and reproductive-harm chemicals

1/2 in Schedule 40 Close Nipple

This steel pipe nipple connects two female-threaded fittings in air, gas, non-potable water or oil lines. The 1/2 in nominal size and NPT threads suit Schedule 40 piping systems. Grade B seamless construction handles 300 psi at 150 °F and 150 psi steam pressure. The black finish protects the globally sourced steel during installation and service.

Threaded male ends for tight assemblies

Both ends carry male NPT threads so the nipple threads directly into couplings, elbows or valves without extra adapters. The close length of 1 1/8 in overall keeps the assembly compact where space between fittings is limited. Electric resistance weld seams maintain wall integrity under pressure. No soldering or flanging is required, freeing up time on the job.

Pressure headroom for standard service

Rated at 300 psi for water, oil, air and gases at 150 °F, the nipple covers most residential and light-commercial distribution pressures. Steam service is limited to 150 psi, so high-pressure steam lines need a different component. The 53/64 in outside diameter matches Schedule 40 dimensions for consistent flow area. Not suited for potable water or applications exceeding the stated pressure and temperature limits.

Questions about this item

How long does the 1 1/8 in close nipple last under sustained 300 psi pressure at 150 °F?

The Schedule 40 steel nipple is rated for 300 psi at 150 °F; seamless construction and Grade B material maintain integrity during continuous operation at that limit.

Does the black-coated steel nipple radiate noticeable heat or make noise when carrying 150 psi steam all day?

The 1/2 in NPT nipple has no moving parts; it conducts steam temperature quietly and the black finish does not add audible vibration or extra surface heat.

What thread sealant or mating fittings must I already have to install this 1/2 in NPT male nipple?

You need compatible 1/2 in NPT female fittings and thread sealant rated for 300 psi air, gas, oil or non-potable water service.
