Durable drain test plug for sealing 38mm pipes. Flexible rubber design for watertight dry testing.
The Monument 1374N Drain Test Plug is a durable and flexible solution for plugging drains and pipes during testing and repair. Crafted with high-quality rubber and featuring a removable top cap, this plug ensures a watertight seal for leak-free dry testing of plumbing systems.
Easy to Use
Simply insert the plug into the pipe end that requires repair or replacement. Turn the wing nut knob to depress the rubber cone, causing it to expand and form a secure seal. This makes it ideal for temporary isolation of pipes during maintenance or inspection.
Applications
Designed for small pipes up to 38mm (1½ inch), this plug is perfect for use on systems such as copper pipes. However, it is important to note that it cannot be used for air testing by itself.
