You May Also Ask

Can the BOOKOO Tee be used with non-BOOKOO pressure sensors?

Compatibility depends on matching thread sizes, but most non-BOOKOO pressure sensors are not guaranteed to work.

If attempting integration, measure threads carefully, seal unused ports, and proceed with caution.

For safe and optimal performance, we recommend using the Tee with official BOOKOO EM.

See details in our Help Center.

What should I do if water leaks from the Tee connection?

Check the O-ring and replace if damaged, or try using two O-rings for a tighter seal.

You can also apply waterproof or PTFE tape to the threads.

If leakage persists, contact our Help Center for support.

How do I fix a tilted pressure gauge after installation?

If the gauge doesn’t face forward, slightly loosen its connection on the Tee and rotate until the 0‑mark is level.

The Tee’s O-rings and sealing rings allow adjustment without over-tightening.

Perform a blind basket test to check for leaks; use PTFE tape if needed.
