Compatibility Checks for Online Orders

Online customers often want to confirm the O-136 will fit their pump lid before checkout. This section outlines what to verify.

How can I confirm the O-136 fits my Ultra Flo pump before ordering?

Check your pump lid for markings referencing Pentair 39300300 or confirm that your system uses an Ultra Flo lid design. If so, the O-136 is the correct replacement.

Will this O-ring work on all Ultra Flo lid designs?

Yes, Ultra Flo lids use a standardized groove dimension, and the O-136 is molded to match that profile. It provides consistent sealing pressure under normal pump operation.

Can replacing the O-136 help resolve priming or suction issues?

Yes, a worn lid seal often allows air into the pump. Installing a new O-136 helps restore stable suction and improves pump priming.

Installation and Setup After Delivery

This section helps online customers install the O-ring properly and confirm correct sealing after installation.

How do I install the O-136 once it arrives?

Clean the lid groove, apply a small amount of silicone-based lubricant, and press the O-ring evenly into place. Make sure it sits flat and is not twisted. Reinstall the lid for a secure seal.

What should I check after installing the new lid O-ring?

Ensure the pump primes quickly and runs without visible air bubbles circulating in the basket. A consistent water level inside the pump pot indicates proper sealing.

How long will the O-136 last under normal use?

The chemical-resistant elastomer offers long service life in chlorinated or saltwater environments. Inspect it periodically for compression or cracking.
