Extended Product Information

FAQs

Is this cap suitable for permanent installation?

No, the S23MR is specifically marketed as a temporary blanking off cap for use during maintenance or renovation.

Can I use this on a 1.5-inch pipe?

No, this product is designed exclusively for 1.25-inch waste pipes and will not fit larger or smaller diameters.

Does it require Teflon tape?

Generally, no. The cap is designed to provide an effective temporary seal without the need for additional sealants or tapes.

Is the material resistant to cleaning chemicals?

The cap is made from durable materials resistant to standard site conditions, but it is not intended for exposure to harsh chemical solvents.

Can this be reused?

Yes, due to its durable construction, the cap can be removed and reused across multiple different projects.

Troubleshooting

Cap does not thread on properly

Verify that the waste pipe diameter is exactly 1.25 inches and ensure there is no dried adhesive or grit in the pipe threads.

Odor is still present

Ensure the cap is tightened fully; if the pipe thread is damaged or misshapen, the cap may not form a complete seal.

Pros and Cons

Pros

  • Simple and fast installation process
  • No specialized tools required for application
  • Highly durable for demanding work environments
  • Prevents harmful debris from entering plumbing systems

Cons

  • Designed for temporary use only
  • Limited to 1.25-inch pipe diameter
  • Not suitable for high-pressure water systems

Setup, Compatibility & Care

To install the S23MR cap, ensure the end of your 1.25-inch waste pipe is clean and free of excessive buildup. Simply align the cap with the pipe threads and rotate clockwise until hand-tight. Do not over-tighten with wrenches, as manual pressure is sufficient to secure the seal. Regarding compatibility, this component is strictly intended for 1.25-inch standard waste piping. When finished with your project, remove the cap, wipe it clean with a damp cloth if necessary, and store it in a dry location to maintain its condition for future jobs.
