Stainless-steel 90-degree coupler with 3/4-inch hose barb for diesel exhaust fluid up to 50 psi

  • Stainless steel body resists corrosion for long service life
  • Viton seals handle fluids from 12 °F to 104 °F
  • 90° outlet angle eases routing in tight spaces
  • 3/4 in hose barb gives secure, leak-free connection
  • ISO 22241 compliant for diesel exhaust fluid use

Piusi F1891000A Coupler Stainless Steel 90 Outlet

This Piusi coupler connects fluid transfer lines in automotive and industrial plumbing systems. Its stainless steel body and Viton seals suit diesel exhaust fluid and other compatible media. The 90-degree outlet angle routes hose neatly in tight engine bays or tank installations. Installers working with 3/4-inch hose barbs will find the barbed thread matches directly.

Capacity and headroom

The coupler operates between 12 and 104 degrees Fahrenheit and withstands up to 50 psi working pressure. Wetted materials include EPDM, polypropylene and stainless steel for broad chemical resistance. It connects a 2 1/2-inch tote thread to a 3/4-inch hose barb in one fitting. Systems exceeding the temperature or pressure range need a different component.

ISO 22241 compliance

The fitting meets ISO 22241 for diesel exhaust fluid handling, confirming material purity for DEF systems. Non-DEF applications should verify fluid compatibility with the listed wetted materials. Buyers who need a straight outlet or a different thread size must select another model.

Questions about this item

Will the 90-degree outlet on this Piusi F1891000A coupler clear the side wall of my existing IBC tote?

The outlet is fixed at a 90-degree angle and threads onto a 3/4-inch hose barb; measure the tote clearance against that fixed bend to confirm fit.

How can I verify the Viton seal is holding at the 3/4-inch hose barb after installation?

Pressurise the line up to the 50 psi rating and inspect the barb joint; no fluid should appear at the Viton seal between 12 and 104 degrees F.

Does the box include the 2-1/2-inch tote adapter or only the 3/4-inch hose-barb coupler?

The supplied coupler has a stainless-steel body, Viton seal and 3/4-inch hose barb; a separate 2-1/2-inch tote-thread adapter is required for tote connection.
