The Tempest oil filter wrench has a unique built-in ratcheting mechanism and a pre-set torque arm to accurately tighten oil filters to the required torque. The tool fits all standard general aviation aircraft oil filters and has a solid lever-arm with a knurled grip to make oil filter installation and removal a snap! The wrench is compact for areas of limited access and easily fits filters in tightly cowled aircraft. Once the new filter is ready for installation, reverse the wrench and ratchet the filter securely back into place. When the pre-set torque limit of 17 ft/lbs is reached, the user will feel a slight “break” or “click” in the handle. No other torque tools are required. 2 lbs (1Kg) shipping weight.
