1) Cut and clean the pipe end to be sealed, ensuring it is square. 2) Check that the pipe diameter matches 3/4 inch and is free of burrs. 3) Align the plug with the pipe and press firmly until it seats fully in place. No tools are required for typical push-fit installation. 4) After installation, inspect for leaks and recheck if pressure is applied.

Use it to cap or seal off a 3/4" PPR pipe end, to temporarily or permanently close a branch, or to connect/disconnect sections in hot or cold water systems in both indoor and outdoor settings.

Yes, the plug is designed to be disassembled for cleaning and maintenance. Reuse is generally possible as long as the seal remains intact and the plug seats correctly; inspect for any wear or damage before reusing.

It’s built from high-grade PPR material, offering corrosion resistance, good temperature tolerance, and leak/pressure resistance. The ergonomic design ensures a precise fit and easy handling.

Yes, within its rated range of -20°C to +90°C, it can be used in hot water applications as part of a PPR piping system.

Besides the 3/4" version, Thomsun offers other sizes such as 1/2" and 1" PPR plugs to fit different pipe diameters. For these alternatives on Fepy, see: 1/2" PPR Plug: https://fepy.com/product/thomsun-ppr-plug-12-inch and 1" PPR Plug: https://fepy.com/product/thomsun-ppr-plug-1-inch

Compared with other sizes in the Thomsun PPR Plug range (e.g., 1/2" and 1"), this 3/4" version offers a middle-ground solution for mid-sized piping. The core advantages—push-fit installation, corrosion resistance, and heat tolerance—are common across the line. For size variants, see the 1/2" and 1" options linked above.

Periodically disassemble if needed for cleaning, inspect the seal and seating area for wear, and reassemble ensuring a snug fit. Keep fittings clean and free from debris that could affect sealing performance.

After installation, pressurize the system and look for any signs of leakage at the joint. If needed, apply a soapy water check around the plug to identify slow leaks and reseat if necessary.
