SurePress® is an innovative line of press fittings that visually confirms a pressed connection. Green indication fills windows once pressed, confirming a successful seal. This allows installers and inspectors to quickly identify if a fitting has been pressed prior to pressure testing. Simply press the fitting, see green and go!

A copper press coupling is a fitting that quickly joins two copper pipes end-to-end without soldering. It has an internal stop that ensures both pipe ends insert to the proper depth. Plumbers use press couplings to create a secure, leak-proof seal in seconds, cutting installation time by up to 60% compared to traditional soldering homedepot.com . This flame-free method is safer and faster for joining copper pipes in plumbing and heating systems.
To install, cut and deburr the copper pipes, then fully insert the pipes into each side of the SurePress coupling until they meet the internal stop. Attach the correct size press tool jaws and squeeze each end. The pressing tool mechanically crimps the coupling onto the pipe, compressing the EPDM O-ring inside to create a permanent seal. The process takes only a few seconds per side. SurePress couplings feature green visual indicator windows that fill in when properly crimped, so you can instantly verify the connection is fully pressed.
Yes – SurePress couplings are engineered for professional reliability. When pressed correctly, they hold up to 300 psi of water pressure, equivalent to or exceeding the pressure rating of soldered joints. They are made of lead-free materials and use NSF-certified O-rings suitable for potable water. SurePress fittings are listed to UPC/cUPC and other applicable standards, so they meet plumbing code requirements. The green press-confirmation band provides extra assurance that each coupling has been pressed prior to pressure testing, helping avoid missed connections.
No special proprietary tool is needed. SurePress couplings are compatible with all major brand press tools. This means contractors can adopt SurePress without investing in new pressing equipment. Just be sure to use the correct jaw size for the coupling (e.g. ½”, ¾”, 1”) and follow the usual safety checks (properly calibrated tool, etc.) before pressing.
A slip press coupling (also called a repair coupling) is a copper press coupling with no internal stop. It can slide freely over pipe ends, making it ideal for repairs. Plumbers use slip couplings to fix a broken section of copper pipe because the fitting can be slid completely onto one pipe, then pulled back over the joint. This allows connecting pipes that cannot be flexed apart. The SurePress slip coupling creates the same secure, leak-tight connection as a standard coupling, but with the ability to join pipes in tight spaces or repair situations where an internal stop would get in the way.
Installation is similar to a regular coupling with a slight difference: first slide the SurePress slip coupling entirely onto one pipe end (since there’s no stop, it will move freely). Next, align the second pipe end and slide the coupling back until it is centered over the gap. Marking the insertion depth on the pipes beforehand is recommended to ensure the coupling ends up properly centered. Once in position, use the press tool to crimp both ends of the coupling. Each end is pressed just like a standard fitting, creating a permanent seal. The SurePress visual indicator bands will turn green on both ends once pressed, confirming the repair coupling has been securely crimped in place.
Yes. A SurePress slip coupling forms a permanent, leak-proof joint equivalent to a coupling with a stop. The absence of a stop does not affect the seal – it simply allows axial movement for installation. The same EPDM O-rings and copper/brass construction are used, so the pressed connection holds the full pressure rating (up to 300 psi water) just like other SurePress fittings. Once both ends are pressed, a repair coupling will handle pressure and vibration as reliably as a normal coupling. The key is to press both ends fully; the green indicator on each end will show you’ve made a complete press.
Yes, one advantage of press fittings is that they can often be installed on pipes with a small amount of water present. You should shut off the water flow and relieve pressure, but the pipe doesn’t have to be bone dry. Unlike soldering, which fails if water is in the line, pressing can seal even with residual moisture. This means in an emergency repair you can use a SurePress slip coupling to quickly fix a leak, even if the pipe is still dripping. The press connection will seal the pipe within seconds, allowing you to repair connections wet or dry without waiting for the pipe to fully dry out.
