Product Information

Full details

The McAlpine Rubber O Ring Seal (P-Or-Showertrp) is a high-quality replacement component designed specifically for plumbers and DIY enthusiasts working on shower drainage systems. It provides a reliable, watertight seal for STW dip tubes, effectively preventing leaks and ensuring your shower trap functions correctly. While this seal is highly durable and resistant to wear and tear, it is exclusively engineered for McAlpine STW series fittings, meaning it will not be compatible with generic or non-McAlpine shower traps.

Extended Product Information

FAQs

Is this seal compatible with other brands of shower traps?

No, this O-ring is specifically engineered for McAlpine STW series dip tubes and may not provide a watertight seal on other brands.

Do I need any tools to install this seal?

No, installation is usually a manual process. You should only use your hands to tighten the collar to avoid cracking the plastic parts.

How often should I replace the O-ring?

There is no set schedule, but it is recommended to inspect the seal whenever you deep-clean your shower trap or if you notice signs of leakage.

What is the material of the seal?

It is made of high-quality, durable plumbing-grade rubber designed to resist chemical erosion and mechanical stress.

Can I use plumbers' grease on the seal?

Yes, a light coating of silicone-based plumbing grease can help maintain the integrity of the rubber and make future maintenance easier.

Troubleshooting

Leak persists after installing the new O-ring

Ensure the dip tube collar is screwed on tightly and that the O-ring was not pinched or twisted during installation.

Difficult to tighten the dip tube collar

Apply a tiny amount of silicone-based plumbing lubricant to the new O-ring to help it slide into place smoothly.

Pros and Cons

Pros

  • Specifically designed for a perfect fit with McAlpine STW dip tubes
  • Made from long-lasting, industrial-grade rubber
  • Prevents costly water damage caused by leaks
  • Highly affordable and easy to replace

Cons

  • Not compatible with third-party or non-McAlpine shower traps
  • Requires proper seat alignment to function correctly
  • Must be replaced if the rubber becomes brittle over time

Setup, Compatibility & Care

  1. Setup: Begin by unscrewing the collar of the shower trap to remove the existing dip tube. Remove the old, worn O-ring, ensuring the channel is clear of debris or lime scale. Slide the new McAlpine O-ring into the groove, ensuring it is seated flat and not twisted. Reinsert the dip tube and tighten the collar by hand until secure.
  2. Compatibility: This product is explicitly for McAlpine STW shower traps. It is not designed for basin waste or kitchen sink applications.
  3. Care: To extend the life of your O-ring, avoid using harsh chemical drain cleaners, as they can cause the rubber to degrade prematurely. If you need to clean the trap, remove the dip tube gently and rinse the seal with warm soapy water.
