Larger 1/2″ D.O.T. air-line connections get their own dedicated service assortment with HB3001-011. Inside are 21 brass push-in fittings selected specifically for 1/2″ tubing, eliminating the clutter and wasted inventory that can come from using a multi-size pack when this is the connection size being serviced.
The selection incorporates push-in unions, male connectors and swivel fittings. Components are manufactured to meet or exceed SAE J1131 and FMVSS 106 requirements for D.O.T. air-brake applications.
A rugged IP68-rated waterproof and dustproof compartment case keeps the fittings organized, protected and portable between the shop and service truck.
HB3001-011 is available from Union Hydraulics for technicians who need a deeper working supply of 1/2″ brass push-in connections rather than just one or two pieces of each configuration.
