I hope this is not a dumb question. The 3/8 hydraulic fittings shown are for a BF900 loader. Same hose just opposite sides. The hoses were made at 2 different Oreily's just days apart. I intentionally took the o ring out on left fitting to show difference. Is there a different way I should connect the fitting on the right? A larger washer on outside of them inner piping? Thread sealant? Teflon tape? Thanks for reading the post.
