1, Description

When the sprinkler torque of the sprinkler exceeds 28.5 N·M, the orifice seal will be damaged and cause leakage. In order to control the tightening torque, the company designed and manufactured a special wrench for the glass ball sprinkler. Limit the tightening torque to 10 to 20 N·M and the handle force is 6.5 to 13 kg to protect the sealing performance of the nozzle.

Do not use the sleeve on the wrench handle when using it to avoid damage to the glass ball sprinkler or cause leakage.

2. Features

The surface of the special open-end wrench is small in chrome plating, light in weight, easy to carry and easy to protect, and protects the glass ball sprinkler when installed. Improved, multiple uses will not be deformed.
