These Miniature Straight Thru-Panel Adapter fittings are 1/4-28 UNF (Unified National Fine) in the middle to fit with the included 1/4-28 UNF Hex Nut, and 1/8" OD Hose-Barb on each end to fit with 1/8" ID hose or tubing. The 1/4-28 UNF will fit through a 1/4" bore hole, to sit up with the hex on the fitting, and be secured with the Hex Nut on the other side. The hex on the fitting measiures and just only creates a minimal flange; not enough for a custom washer (no option available for this fitting). Both the fitting and the hex nut are made from Black Nylon.

These are multi-purpose fittings and may possibly be used for Automotive, Boat (Marine), Hydroponic, Irrigation, Pneumatic, Agriculture, and Aquarium applications.

*Please note: stock image may be slightly different than actual item. A newer mold has changed the hex portion, on the main fitting piece, to have a channel around the middle. This does not affect integrity, though. Other than that, the rest of the dimensions are the same.
