bohot sahi lock ring hai
was skeptical whether this ring nut would fit my older pool valve setup without leaking, but it actually screwed on smooth. koi tools ki zarurat nahi padi cleaning ke time, bas hath se twist karke khol liya. rly happy with how it holds pressure now.

does the job well
got two of these for our pool setup since we needed replacements for the old ones that got stuck. delivery was fine and the cpvc build feels quite solid against chemicals. took a bit of effort to fit properly into the existing piping but no leaks so far.
FAQs
Are you replacing a cracked lock ring or fixing a leak?
Yes, this replacement lock ring is specifically designed to resolve issues caused by cracked plastic nuts or failing seals. Replacing the worn component restores a tight clamp on the valve lid to stop leaks effectively.
What pool valve models are compatible with this lock ring?
This lock ring is compatible with select Waterway serviceable swing check valves and TruSeal pool plumbing systems. Always verify your existing part number or owner manual before installation to ensure a correct fit.
Should I use tools to tighten this CPVC lock ring?
No, you should always hand tighten this component only. Using wrench tools can apply excessive force, which may crack the plastic threads on the valve body.
