Komatsu ORFS fitting couplings are machined with a o ring flat face seal groove, along with metric threads, it is face seal type of hydraulic fittings, also called flareless fittings, to connect hydraulic hoses and hose fittings.
Komatsu flat face fittings is metric o-ring face seal fittings, metric orfs fittings is different from british flat face adapter and SAE UNF thread orfs adapter.
As showed in this drawing, metric thread o-ring face seal fittings to BSPP adjustable end o-ring plus retaining ring face. We can design metric seal lok tube fittings for Japanese industrial standard hydraulic system.
