Boshart SS 1" 304 Stainless Steel Threaded Fitting, ISO4144

The Boshart 1" 304 Stainless Steel Threaded Fitting family is a rough-in solution for plumbers and contractors who need a corrosion-resistant connection point in stainless steel piping systems. This family is available in two configurations — Cap and Tee — both manufactured to the ISO4144 threaded fitting standard and sized for 1" pipe. Every option in this family is constructed from 304 stainless steel, giving each fitting strong resistance to rust and corrosion in demanding installation environments. Boshart supplies these fittings in bulk packaging of 20 each, making them a practical choice for distributors and contractors stocking rough-in inventory for stainless steel threaded piping runs. Whether the application calls for a terminating Cap or a branch-off Tee, the shared 1" trade size, 304 stainless steel construction, and ISO4144 thread dimensions ensure consistent fit and finish across the family.

Key Features

  • Trade Size: 1" connection sized for use in 1" stainless steel threaded piping systems, consistent across both the Cap and Tee configurations.
  • Durable Construction: 304 stainless steel body offers strong corrosion resistance for demanding rough-in and process piping applications.
  • Threaded Connection: Standard pipe threads allow either configuration to be made up with mating stainless steel threaded fittings and pipe.
  • ISO4144 Configuration: Manufactured to the ISO4144 dimensional standard for threaded stainless steel fittings, supporting consistent thread engagement with compatible fittings.
  • Two Configurations Available: Choose a Cap to terminate a threaded run or a Tee to add a branch connection off a straight run of 1" threaded stainless steel pipe.
  • Bulk Packaging: Packaged 20 each, suited to contractor and distributor stocking needs for stainless steel threaded fittings.

Boshart SS304CA-05 – Frequently Asked Questions

1) Will a Boshart 1" 304 stainless threaded fitting mate with my existing 1" stainless pipe threads?
Yes, as long as the run is 1" trade size threaded stainless. The Boshart 1" fittings are built to the ISO4144 dimensional standard for threaded stainless steel fittings, so thread engagement is consistent with mating ISO4144 stainless fittings and 1" pipe. Two configurations are made: a Cap (SS304CA-05) to close off the end of a run, and a Tee (SS304T-10) to take a branch off a straight run.
2) Cap or Tee, which Boshart 1" stainless fitting do I need?
Use the Cap if you are terminating a 1" threaded stainless run, for example closing off a stub-out or a test point. Use the Tee if you need to pull a branch off a straight 1" run. Both share the same 1" trade size and 304 stainless body, so they make up into the same piping system.
3) Is 304 stainless the right material for a corrosive or wet process line?
304 stainless gives strong rust and corrosion resistance, which is why these 1" threaded fittings get specified for process and utility piping, commercial and industrial plumbing, and rough-in runs where galvanized or black iron would not hold up. For chloride-heavy or marine service, buyers typically step up to a 316 alloy instead.
4) What thread sealant should I use on these stainless threaded fittings?
Boshart calls for using Gray Stainless Steel PTFE Tape together with Gray Magic Pipe Thread Compound when joining the Cap or the Tee to mating stainless threaded fittings. Stainless threads gall easily, so the tape plus compound combination is what keeps the joint making up cleanly and sealing.
5) What are the Boshart part numbers for the 1" stainless cap and tee?
The 1" 304 stainless cap is SS304CA-05 and the 1" tee is SS304T-10. Both are ISO4144 fittings in the same 1" trade size, so a distributor can order them as a matched pair for a stainless threaded run.
6) How are Boshart 1" stainless caps and tees packaged for stocking?
Bulk, 20 each per pack. That suits distributors and contractors keeping rough-in inventory on the shelf rather than buying fitting by fitting.
7) Do these Boshart stainless fittings carry a Prop 65 warning?
No Prop 65 warning applies to the Boshart 1" 304 stainless threaded caps and tees. They are made in China.
