B&K / Mueller Industries Test Plug

4 in test plug with galvanized steel flanges and a molded rubber gasket.

Easy installation and a clean, positive seal.

Product Overview:

When a pipe opening needs a solid hold, this test plug keeps the job simple. It gives you a 4 inch fit with galvanized steel flanges and a molded rubber gasket that seats tight in soil, plastic, or copper pipe. That matters when you want the line closed off without fuss, and without dragging in plaster or cement. You get a tool that feels straightforward in the hand, goes in fast, and settles with a quiet, snug grip. Picture the line sealed, the work area staying tidy, and the next step moving along without the usual headache.

Key Features:

• Molded rubber gasket: It forms a positive seal in soil, plastic, or copper pipe, so you can set it once and keep moving.
• Galvanized steel flanges: The metal flanges add a sturdy feel and help the plug stay composed under everyday jobsite handling.
• Easy installation: You spend less time wrestling parts into place, and that makes the whole task feel a lot less fussy.
• 4 inch size: The 4 inch fit gives you a direct match for the job, which helps cut down on guesswork.
• 6 per carton: With six in a carton, you have extras ready when the day throws you another line to close off.
