SKU CH-YVHB-0VHHK

Stainless steel 90-degree coupler with 3/4-inch buttress thread for diesel exhaust fluid systems

  • Stainless-steel body resists corrosion for longer service life
  • EPDM seal protects against fluid contamination during transfer
  • 90° outlet eases hose routing in tight spaces
  • 3/4-inch buttress thread fits standard DEF tote connections
  • ISO 22241 compliance confirms suitability for diesel exhaust fluid

Stainless-Steel DEF Coupler

This 90-degree stainless-steel coupler connects a 3/4-inch buttress-threaded hose to a 2-inch tote fitting. It is built for diesel exhaust fluid transfer and meets ISO 22241 compliance. The EPDM seal resists fluid degradation and protects the system from contamination.

Buttress Thread and ISO Limits

The buttress thread profile only mates with matching 3/4-inch buttress connections; it will not seal on NPT, BSP or quick-disconnect fittings. ISO 22241 governs fluid purity and component materials, so the coupler must stay dedicated to DEF service and cannot be reused for fuel, oil or coolant lines.

3/4-Inch Flow and Compatibility

The 3/4-inch hose bore handles standard DEF pump flow rates without restriction and the stainless body resists crystallisation buildup. It is not suited for larger-diameter hoses or high-volume bulk transfer that exceeds the 3/4-inch passage. Buyers needing a straight-through or larger-bore connection cannot use this fitting.

Questions about this item

Should I choose the 3/4 in buttress version or a different thread size?

This model has a 3/4 in buttress thread and a 2 in tote connection; select it when your equipment matches those exact sizes.

What does the 90° outlet do once installed on a DEF system?

The 90° outlet routes the hose at a right angle, reducing kinks and easing routing in tight pump compartments.

How does the ISO 22241 compliance affect the buttress connection in practice?

ISO 22241 certifies the wetted stainless steel and EPDM seal for diesel exhaust fluid, so the buttress thread will not contaminate the fluid.
