One cell from bar stock to tested set.

Machining, sealing, assembly and leak testing sit on one production line — so every DryLink UQDB and UQ04 set has its valve seats ground to ±0.01 mm, its seal compounds lot-traced and its leak test passed before the carton is sealed. Drawings in, a priced answer in 48 hours.

Four Cells, One Line

Four capabilities behind every coupling.

OCP UQD Rev 1.0 sets the floors buyers test against — 5000 mate cycles, 100 psi working pressure, 300 psi burst. The four cells below exist to clear those floors on every batch we ship, not just on the datasheet.

Cell 01 · Machining

Precision CNC Machining

3-, 4- and 5-axis cells turn 316L, brass and aluminum bar into valve bodies, manifold cores and 1U-envelope hardware. Sealing faces are ground — not turned — to a ±0.01 mm tolerance, because on a dry-break coupling the metal valve seat, not the elastomer alone, does the sealing.

Cell 02 · Sealing

Sealing Technology

EPDM is the standard compound for water-glycol service from -40 to +120°C, with FKM, FVMQ, NBR and HNBR options spanning -55 up to +200°C. Compounds are qualified against the DOWFROST LC 25 and JEFFCOOL ISF-25 coolant families named in the OCP specification before they enter a set.

Cell 03 · Assembly

Automated Assembly

Valve stacks close under calibrated torque with batch-recorded values, and red and blue seal rings mark hot and cold sides so a reversed set is visible before coolant is ever in the line. Each set leaves its cell carrying a serial linked to its component lots.

Testing & Cleanliness

Every set passes vacuum-decay leak testing, verified on helium benches with 5×10⁻¹² mbar·l/s detector-class sensitivity. Cleanliness is held to ISO 4406 18/16/13 particle codes and surface finishes face 48 hours of neutral salt spray — with the report shipped inside the carton.
