Best Lubricant for Pool Strainer O-Rings: Silicone Grease & More

* Silicone grease: This is the most common and recommended lubricant for pool strainer o-rings. It is safe for use with all types of o-rings and will not deteriorate them over time.

* Teflon tape: This is another good option for lubricating pool strainer o-rings. It will create a tight seal and prevent leaks.

* Petroleum jelly: This is a temporary lubricant that can be used in a pinch. However, it will eventually break down and need to be replaced.

To lubricate your pool strainer o-ring, simply apply a thin layer of the lubricant to the ring. Be sure to coat the entire surface of the o-ring, including the inner and outer edges. Then, reinsert the o-ring into the strainer housing and tighten the cap.
