Overview

One bad foot of hose should not condemn twenty good ones. This air brake hose union distributed by FleetPro Parts & Tires joins two ends of 1/2 in inner diameter hose into a single sealed line, which turns a rub-through in the middle of a long run into a five-minute cut-and-splice. On the big 1/2 in supply lines that is the difference between a shop visit and a repair you finish yourself. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Splice It and Roll: The 1/2 In Hose Union Advantage

This union is reusable fitting hardware for field-assembled DOT rubber air brake hose, the same family as the couplings and sleeves that build a hose end โ€” except both sides take hose instead of one side taking a port. Cut back past the damage on each side until you are into clean, undamaged rubber, assemble the union, then re-clamp the run so the new joint rides supported rather than hanging in the air where it will work itself loose.

Keeping one of these in the side box is cheap insurance on any truck plumbed with 1/2 in ID hose, because roadside air leaks never happen conveniently. At FleetPro Parts & Tires we stock the small hardware that gets trucks moving again instead of onto a hook. This Automann hose union is a direct replacement for highly searched industry numbers including Euclid E8601, 33808BY08, 62RB8, 107701 and 500088, and it replaces the earlier 177.7025.

Key features
  • Splice Instead of Replace: Joins two 1/2 in hose ends so a rub-through in the middle of a long run costs a fitting, not the whole line.
  • Field-Assembled Hardware: Part of the same reusable system as the couplings and sleeves, so the repair happens on your bench.
  • Sized for 1/2 In ID Hose: Matched to hoses with a 1/2 in inner diameter so both ends seat and seal correctly.
  • Wide Euclid Interchange: Direct replacement for Euclid E8601 plus 33808BY08, 62RB8, 107701 and 500088.
  • Roadside Spare: Small enough to live in the side box, which is where you will want it when a line lets go.
