6 in Pipe Plug, 3.75 in Height

The Cherne 270253 is a mechanical pipe plug designed to seal 6 in nominal pipes from the inside. It fits pipe inside diameters between 5.77 in and 6.08 in and has an overall height of 3.75 in. The plug uses a zinc wing nut to expand an ABS sealing plate against the pipe wall. It is intended for temporary or permanent drain isolation in plumbing systems.

Suits 6 in pipes with 5.77–6.08 in ID.

This plug suits installers who need to block a 6 in line without a bypass or test port. It does not suit pipes outside the stated inside diameter range, nor applications that require a water fill hose or padlock provision. Builders needing a bypass connection or a different pipe size must select another product.

Seals 5.77–6.08 in inside diameter

The single specification that decides fit is the pipe inside diameter range of 5.77 in minimum to 6.08 in maximum. The plug expands internally to seal within this window. Maximum back pressure ratings are 17 psi for air and 40 ft of head for water, but diameter compatibility is the decisive factor.

Questions about this item

What pipe inside-diameter range does the 6 in Cherne 270253 plug seal?

It seals pipes with an inside diameter between 5.77 in and 6.08 in, matching the stated 6 in pipe size.

How is the wing-nut plug installed and what step is often missed?

Insert the plug into the pipe, then tighten the zinc wing nut by hand until the ABS plate expands and grips the pipe wall; the step often missed is confirming the seal sits fully inside the pipe before pressurising.

When should the ABS sealing plate be replaced on the Cherne 270253?

Replace the plate if it shows cracks, permanent deformation, or if the plug no longer holds the rated 17 psi air or 40 ft of water head pressure.
