Specifications and configuration
Reference — FITOK S4-UQD02-ST7-D-BL
| Parameter | Documented value / configuration |
|---|---|
| Manufacturer model | S4-UQD02-ST7-D-BLConditions: scope: Exact reference order code; no site stock claim |
| Termination material | 304 stainless steelConditions: scope: Maker specifies termination material; confirm full wetted material bill for purchase |
| Port connection | SAE/MS male straight thread 7/16-20Conditions: scope: Plug tail port, not the mating socket port |
| Configuration decoding | S4 = 304 SS; UQD02 size; ST7 = 7/16 in SAE/MS straight thread; D = valved plug; BL = blueConditions: scope: Decoding of an actual listed model; catalog cautions not to freely combine code elements |
| Equivalent flow diameter | 3 mm nominal equivalent diameter for UQD02 pairConditions: scope: UQD02 size designation, not a measured bore of this isolated plug |
| Published series pressure | 16 bar maximum working pressure; 48 bar minimum burst pressureConditions: scope: Maker UQD series published values; complete mated connection and coolant must be checked; burst is not working duty |
| Plug reference dimensions | L = 1.06 in (27.0 mm); L2 = 0.36 in (9.1 mm); wrench flat F = 0.55 in (14.0 mm)Conditions: scope: Catalogue reference dimensions; page 4 states dimensions may change |
| Standard series seal | EPDM O-ring listed as UQD series standard sealConditions: scope: Confirm actual ordered sealing option and coolant chemistry |
Manufacturer reference configuration. Values and conditions apply to the named reference; the supplied configuration requires separate confirmation.
Overview
This is the valved plug half of a manually mated UQD02 liquid connection. The blue ring can identify a circuit, but the complementary socket and its tail must be selected separately.
Construction and interfaces
The pictured plug has a flat-face valved nose, a 7/16-20 SAE/MS male-threaded tail and a blue identification ring. The maker lists 304 stainless steel termination material.
Selection
Use the exact plug code or a controlled equivalent drawing, then confirm the matching socket, mating standard revision, fluid, pressure, temperature and required hose or manifold port.
Configuration options
The official code scheme includes other nominal sizes, red or blue rings and alternate material or tail choices. These are separate ordered configurations, not automatically interchangeable versions of this plug.
Application limits
The 16 bar working and 48 bar burst values are maker-published series conditions for the complete connection, not a site supply guarantee. Dimensions are catalogue references and may change.
