This end plug closes the end of 1/4″ OD misting tubing to stop leaks and keep pressure where you need it. Use it to finish a run, isolate a section for testing, or cap lines during seasonal shutdowns without cutting or special tools.

This end plug works with common 1/4″ OD misting tubing. Match the tubing and all fittings to your system’s pressure rating.

For seasonal shutdowns, depressurize the line and remove the plug. Store it clean and dry. In spring, inspect the tube end for wear, cut a fresh end if needed, and re-seat the plug before testing.

Prepare the tube end, push the plug on until fully seated, then test at normal pressure. Re-seat if you see any drip.
Cut Tubing Square
Use a sharp tube cutter to make a clean, square cut. A square cut helps the seal seat evenly.
Deburr & Clean Ends
Remove burrs and wipe the tube end. Keep the surface round, smooth, and free of dust.
Push to Full Seat
Insert the tube straight into the end plug until it stops. A firm push is needed to pass the internal grip and seal.
Pull Test to Confirm Grip
Gently pull back on the tube. It should not come out. If it moves, push further to seat fully.
Secure Nearby Tubing
Add a nearby mount or clip to remove strain on the plug. This keeps the cap steady under load.
Bring System to Operating Pressure
Start the pump and reach normal pressure. Watch the plug and nearby joints.
