Food and beverage couplings (NSF)
UDC
The Universal Dispensing Coupler (UDC) links dispensing lines to containers with a 38 mm fitment neck, including bag-in-box, flexible and rigid packaging. Automatic flush face valves keep spillage low on disconnection, and a large shrouded thumb latch makes the coupler easy to grip and operate. The NSF-listed parts are made of polypropylene or acetal (POM) with EPDM, silicone or NBR seals and work from vacuum to 1.03 bar when coupled, at 0 to 71 °C.

Frequently asked questions
- Which containers does the UDC series fit?
- Bag-in-box as well as flexible and rigid packaging with a 38 mm fitment neck. The connection is made without tools.
- What do the flush face valves do?
- They close automatically and sit flush on disconnection, so very little liquid is left on the coupling during a changeover and spills are avoided.
- Which seal material should I choose?
- EPDM, silicone and NBR (Buna-N) are available in FDA-compliant grades. The choice depends on compatibility with the medium being dispensed and the requirements of your equipment.
- Are UDC couplings available with RFID?
- Yes, the series is also offered with IdentiQuik RFID technology, which identifies the connected medium or container and verifies that the correct line is connected.
- What pressure ratings apply?
- Coupled, the UDC works from vacuum to 1.03 bar, and an uncoupled cap holds up to 0.34 bar. The temperature range is 0 to 71 °C.
