PVC Compression Coupling - How to Use Video Guide
What You'll Learn
- How to install a compression coupling without glue
- When to use compression fittings vs glued fittings
- Proper tightening technique for leak-free connections
Quick Guide
PVC compression couplings are the fastest way to repair broken sprinkler lines without gluing. Perfect for emergency repairs or temporary fixes.
When to Use Compression Couplings
- Emergency repairs when you need water running quickly
- Repairs in wet conditions where glue won't work
- Temporary fixes before permanent repair
- Connecting to existing lines that can't be cut
Installation Steps
- Cut pipe ends square and clean
- Slide compression nut and O-ring onto pipe
- Insert pipe fully into fitting
- Tighten nut hand-tight, then 1/4 turn with wrench
Pro Tip: Don't overtighten! Compression fittings seal with O-rings, not thread force. Over-tightening can crack the fitting.

FAQ
Are compression couplings as strong as glued fittings?
Compression couplings are strong enough for most residential sprinkler systems (up to 150 PSI). However, glued fittings are preferred for permanent installations.
Can I use compression couplings underground?
Yes, compression couplings work great underground. Make sure to install them in a valve box for easy access if repairs are needed later.
Do I need Teflon tape with compression fittings?
No, compression fittings seal with O-rings, not threads. Teflon tape is not needed and won't help the seal.
