Technical
How FLEXQ part numbers are built – series, nominal size, connection, valve, size, outlet and options.
Every FLEXQ part number follows the same key. Example: coupling HPT, nominal size 9, hose barb Ø 13, with valve, 90° outlet, with safety lock.
For multi couplings the number describes a complete plate: which side, how many connections and what the plate is fitted with. Machine side and mould side are ordered separately.

| O | Male thread BSP or metric, parallel, with sealing ring |
| T | Male thread NPT |
