An Imperfection On The Sealing Surface Of A Fitting Can Cause It To Leak. And What If It Is A Weld-In Bung? In The Past You Would Have To Replace The Fitting, A Major Headache, But Now You Can Repair It On Location. The Fitting Fixer Utilizes An Inverted Cone, Diamond-Dust Coated Lapping Head To Repair The Conical Surface And Restore The Seal With The Flared Tube. Using This Tool Is Simple. The Damaged Fitting Screws Into A Guide That Holds It In Place. Next, Connect The Lapping Head To A Drill And Spin It Intermittently About A Half Dozen Times. Inspect The Sealing Surface To See If There Are Any Imperfections. If Damage Is Still Visible, Repeat The Lapping Process Until You Have A Clean Surface.

Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
