Nibco C301550P – Frequently Asked Questions

1) What thread does the Nibco TCBR-4 brass end connector use, and will it mate with standard steel pipe?
It is a male NPT thread cut to ANSI B1.20.1, so it threads into any standard female NPT fitting or tapped port. The connection is threaded brass, not solvent weld, so the mating side needs to be female pipe thread.
2) Can I use this brass connector to replace the plastic end connector in an existing Chemtrol union?
That is exactly what it is for. The TCBR-4 is field-assembled into the union in place of a plastic end connector, giving you a metal male NPT tail on a plastic piping union. Nibco directs installers to the Chemtrol technical data sheets, chemical resistance guides and catalogs for engineering and installation detail before you make the swap.
3) What pipe size and schedule does the Nibco TCBR-4 end connector suit?
It is a 2 inch connector, MPN C301550P, built to Schedule 80 piping.
4) Is a brass end connector the right choice, or should I stay with plastic?
Go brass where the union has to take a threaded metal connection or repeated make and break at a pump, valve or equipment tie-in, and where the fluid suits it. Stay with the plastic connector where chemical resistance drives the joint, since brass is a metal wetted part. Chemtrol chemical resistance data is the reference for that call.
5) Does the TCBR-4 come with a union nut, O-ring or gasket?
It is the end connector only, an accessory part for the union. The nut, seal and the mating union half stay with the existing Chemtrol union you are assembling it into, so order any seals you plan to renew separately.
6) What systems is the Nibco TCBR-4 used on?
Commercial plumbing, industrial process, irrigation and pharmaceutical systems, and it is listed for fire protection applications.
