Hose Connector Oxygen - Otto Frei
Meco Midget Torch

Hose Connector Oxygen

Part # 114.178 8 In Stock Weight -- lb / -- g
$8.25
Select Size: 9/16" Nut 1/4" Nipple

Oxygen hose connectors for connecting torches to cut hoses using either USA Standard A (3/8") or USA Standard B (9/16") fittings. The threaded nut secures the connector to the torch inlet, while the barbed nipple is inserted into the hose and held in place with a hose clamp. Three configurations are available to match your torch type and hose inner diameter.

Important: Dimensions listed for nipples refer to the inside diameter of the hose they are recommended for — not the outer diameter of the nipple itself. The nipple diameter is larger than the hose ID it is intended for.
