Flexible Hydraulic Rubber Hose with Olive Inserts

Flexible hydraulic rubber hose connectors use 3/8 inch UNF thread connectors.

How to understand sizes

  • 3/8 inch refers to the diameter of the thread
  • 3/16 inch refers to the width of the pipe that the connector fits over.
  • 1/8 inch NPI refers to the American equivalent of the 3/8 inch thread.
  • Note: Only 3/8 inch American elbows convert 1/8 inch NPI to 3/8 inch UNF

Brass parts include:

  • Adaptor nut
  • Elbow
  • Joiner
  • Shot or long olive nut
  • 3-way
  • 4-way
  • 1/8 inch NPT to 3/8 inch elbow

Flexible rubber hoses are 40cm long.

Brass connectors with olive inserts provide a perfect fit when attaching hoses to hydraulic equipment.

Australia hydraulic calipers have no built olive connection. Use a brass adaptor with an olive seat to connect this trailer brake equipment into service.

If the disc brakes or hydraulic cylinder leaks, then you have likely screwed the 3/8 inch nut on your hydraulic lines directly into a component that requires a nut adaptor to complete the termination.

Disc brakes are steel and coated in Dacroment or gal. Alternatively, they can be stainless.

Further, Couplemate recommends the use of Teflon tape for all fittings.
