Used for straight connection of pipes with the same diameter. The length of the pipes at both ends must be symmetrical during installation to avoid skewed stress.

High-risk operation prohibitions

Use of glue

- It is prohibited to use expired glue or non-PVC special glue (such as ABS glue), otherwise it will cause bonding failure.

Environmental restrictions

- Stop construction when it rains/humidity>70%; low-temperature glue must be used when the ambient temperature is <5℃.

Violent installation

- It is strictly forbidden to use hammers to forcefully insert pipe fittings to prevent the socket from breaking.

Uncured water flow

- Uncured glue will cause "bubbling" and debonding, and must be strictly waited for 24 hours.
