Fittings
High-pressure water fittings
WARNING
Do not tighten a fitting too much. The fitting can fail.
WARNING
High-pressure water fittings are designed to make a tight seal. If a fitting is installed
incorrectly, it can fail.
CAUTION
To prevent causing damage or premature failure, use 2 wrenches when loosening or
tightening a high-pressure connection.
Always tighten fittings to the specified torque.
CAUTION
Do not use an adjustable wrench on high-pressure fittings.
Use a high-pressure antiseize lubricant such as Blue Goop or PURE Goop on
high-pressure water fittings.
Use only enough torque to make a sufficient seal.
Torque values can vary depending on thread condition. A sufficient seal can be made at
values much lower than the maximum values shown in the table.
If a fitting leaks after tightening it to the maximum torque value, disassemble the parts.
Repair or replace parts that show deterioration, corrosion, or damage.
