Spears 4147-007 – Frequently Asked Questions
1) Can I unscrew this CPVC cap later to reopen the line?
No. The 4147 is a socket (solvent-weld) cap, not a threaded plug. Once it is cemented to the pipe the joint is permanent, and reopening the line means cutting the cap off and re-fitting. If you want a removable termination, use a threaded plug and a threaded adapter instead of a socket cap.
2) What do I need besides the cap to finish a capped CPVC branch?
Just the pipe end and CPVC solvent cement (with primer where your local code calls for it). The 4147 socket cap needs no threading, gaskets or mechanical fasteners; cut the pipe square, deburr, and cement the cap on. The socket depth does the sealing, so no thread sealant is involved.
3) Is the Spears 4147 cap suitable for hot water lines?
It is a CPVC fitting, intended for CPVC CTS hot and cold water distribution piping as well as commercial, residential and process piping. CPVC is the material used for hot water CTS plumbing, and the cap matches the pipe it terminates.
4) What is the right fitting to seal off an unused CPVC branch line during a renovation?
A socket-weld cap like the Spears 4147 closes the end of the pipe itself, which is the cleanest way to kill an unused CTS branch or terminate a run on remodel work. It seals the open end against leaks and contamination. If instead you need to close a fitting's open outlet rather than a pipe end, you want a plug, which fits inside the socket, not a cap, which fits over the pipe.
5) Do these Spears CPVC caps come in bulk for stocking?
Yes, the 4147 socket-weld cap is supplied 250 each per package, which is how distributors and plumbing contractors typically stock the smaller CTS fittings.
6) Where can I get exact socket dimensions and weights for Spears CPVC CTS caps?
Spears publishes CTS CPVC dimension data and a product dimensions and weights sheet for the CPVC CTS line, which cover socket depth and laying lengths per size. Those are the documents to check when you are verifying a 4147 cap against the pipe and space you have.
