The polypropylene snap-on strap conveniently snaps on to hang and support CPVC-CTS piping. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. Chlorinated Polyvinyl Chloride (CPVC) has proven to be an excellent material for hot corrosive liquids, hot and cold water distribution, and similar applications above the temperature range of PVC. CPVC will not rust, pit, scale or corrode. CPVC fittings are easy to install and are joined by solvent cementing or threading. NIBCO® plastic fittings are backed by a 5-year limited warranty. Because of its longstanding reputation for innovation and precision in design and manufacturing, NIBCO is the preferred brand in the industry.

Nibco M213400 – Frequently Asked Questions
1) Can I use a plastic snap-on strap on hot water lines, or do I need a metal hanger?
Hot water is what CPVC systems are built for, and the polypropylene snap-on strap is the matching support for CPVC-CTS lines rated to a maximum service temperature of 180 degrees F. It suits hot and cold water distribution runs. Where a run carries compressed air or other gases, CPVC is not the right system at all, so the strap is not the answer there either.
2) Do I need to unhook the pipe to install a Nibco 4724 strap, or can it go on an existing run?
It snaps on. The 4724 is a snap-on design, so it clips over CPVC-CTS pipe already in place rather than requiring you to thread the line through a closed hanger. That matters on a repair or a retrofit where the run is already made up and you are just adding support points or replacing a broken strap.
3) Is the Nibco 4724 strap approved for potable water in a commercial building?
Lead-free is the stated application, and the CPVC product line it belongs to is NSF U.P. Certified and carries NSF/ANSI recognition. System use covers both commercial and residential plumbing, so it is specified the same way in a multi-family or institutional job as in a house.
4) Will a tan CPVC strap match the FlowGuard Gold pipe I am already running?
The 4724 strap is tan, which is the usual colour of CPVC-CTS water distribution pipe, so it blends with exposed runs rather than standing out the way a white or galvanized clamp does. For a property manager standardizing across units, ordering the same strap on every job keeps the exposed piping in mechanical rooms and utility closets consistent.
5) Does a CPVC snap-on strap let the pipe move for thermal expansion?
A snap-on strap holds the line to the structure without clamping it the way a threaded pipe clamp does, so it supports the run at intervals rather than anchoring it rigidly. CPVC moves noticeably with temperature on hot water lines rated up to 180 degrees F, so the usual practice is to support with straps and let the run take up its own expansion between them. Nibco's technical data sheets and catalogs carry the engineering and installation detail for support spacing.
