Drain Stopper with Blanking Cap Brass Wing Nut Rubber Seal Test Plug

6" Drain Stopper with Blanking Cap for Secure Pipe Testing

Need a reliable way to seal a larger pipe before a leak or pressure check? This 6" x 1/2" Drain Stopper (c/w Blanking Cap) is a mechanical drain plug made for plumbers, contractors and maintenance teams working on bigger drainage runs. It works as a drain test plug and a pipe testing plug, giving you a firm closure so you can fill, pressurise and inspect the line with confidence.

The stopper has a thick rubber seal fitted around a strong outer steel collar. Tighten the brass wing nut and the rubber expands outward, pressing tightly against the inner pipe wall to form a watertight seal that holds during testing. This helps you spot leaks early and avoid expensive rework. The zinc plated steel finish resists corrosion, and the threaded centre bolt turns smoothly even after repeated use. The included blanking cap adds extra protection and a neat finish to the assembly.

Easy to fit and remove, this 6 inch drain stopper saves time on every job. No special tools are needed, and the wing nut gives you a firm grip for quick, secure tightening on site.
