|---|---|
| 1/2-inch | 1/16 inch |
| 3/4-inch | 3/32 inch |
| 1-inch | 1/8 inch |
Inspecting the Crimp Connection
As soon as the crimping course of is full, it is essential to examine the crimp connection totally. This ensures that the connection is safe and dependable, stopping leaks and potential system failure.
Listed here are some key steps for inspecting the crimp connection:
1. Visible Inspection
Start by visually inspecting the crimp connection. Search for any indicators of uneven crimping, gaps, or harm to the PEX tubing or crimp ring. Be sure that the ring is absolutely seated and crimped across the tubing.
2. Twist Check
Gently twist the PEX tubing close to the crimp connection. If the connection is safe, there needs to be no motion or rotation. Any motion signifies a weak crimp and will require additional tightening.
3. Pull Check
Grasp the PEX tubing and gently pull on it to check its energy. The connection ought to maintain firmly with none indicators of leakage or separation. This ensures that the crimp is safe and might face up to the strain of the water stream.
4. Hammer Check (Non-obligatory)
For added assurance, you possibly can carry out a hammer check. Flippantly faucet the crimped space with a hammer. If the connection is correctly crimped, there needs to be no motion or deformation. Nonetheless, if the crimp ring loosens or the tubing buckles, it signifies a weak connection.
