Coupler with 90° Outlet and Buttress Thread

The Blue Def DEF744-048 is a stainless steel coupler designed for diesel exhaust fluid systems. It connects a 2-inch tote fitting to a 3/4-inch hose using a buttress thread profile. The 90-degree outlet orientation aids routing in tight plumbing layouts. It is intended for installers and fleet maintenance teams handling DEF transfer equipment.

ISO 22241 Compliance and Wetted Materials

Wetted surfaces are stainless steel with an EPDM seal, meeting ISO 22241 standards for fluid purity. The construction protects the fluid from contamination during transfer. It is rated for compatibility with diesel exhaust fluid only. The design does not support other chemicals or higher-pressure hydraulic circuits.

Questions about this item

Will the 90-degree outlet and 3/4 in buttress thread align with the existing hose on my older DEF dispensing system?

The coupler has a 90-degree outlet with a 3/4 in buttress thread and 3/4 in hose inside diameter, designed to mate with standard 4-pin RSV valves on totes.

How can I confirm the ISO 22241 compliant stainless steel body and EPDM seals are sealing correctly after installation?

Pressurise the line and check the 2 in tote connection and 3/4 in threaded joint for leaks; the EPDM seals and stainless body should hold fluid without weeping.

Does the box include the mating RSV valve or any clamps, or must they be purchased separately?

Only the stainless steel coupler with EPDM seals is supplied; the 4-pin RSV valve, hose clamps and any additional fittings are sold separately.
