Product Review

Fragola Aluminum A-N Adapters and Fittings may look like simple devices, but Fragola takes them very seriously. They have spent several years researching, testing, and retesting to perfect what they feel are the finest adapters and fittings available.

Many people over tighten the aluminum fitting on the adapter, which distorts the 37 degree seat, and may cause a leak. Both the threads and the seat surface face should have a drop or two of oil to smooth the tightening process. Please reference the chart below for the maximum torque specifications for the various size fittings. An alternate method is to bring the nut to "hand tight" and then rotate it another 1/4 turn with the proper wrench.
