A Stauff test point fitting designed for pressure monitoring in hydraulic circuits, the SMK-20-R1/4K-VD-W3 uses an R1/4 threaded connection and size 20 designation, making it compatible with standard Stauff test point couplings and diagnostic equipment across mobile and industrial hydraulic applications. The valve-equipped design supports clean, quick connection and disconnection under pressure, allowing routine pressure checks without interrupting the circuit or disconnecting lines.
Well-suited for use with pressure gauges, data loggers, and diagnostic instruments, this fitting provides a reliable, leak-free interface at measurement points throughout a hydraulic system. Its compatibility with Stauff's established test point system makes it a practical choice for service and maintenance tasks requiring repeatable, accurate pressure access.

Question by: Hugh P on Feb 4, 2026, 3:27 PM
Been using Stauff test points on our machines for years. This one's got the R1/4 thread and size 20 designation, so it'll mate up with our existing Stauff couplings and gauges without any adapters, right?
Answer by: Customer Support on Feb 6, 2026, 1:56 PM
Correct on both counts. The R1/4 threaded connection and size 20 designation are part of Stauff's established test point system, so it'll pair directly with standard Stauff test point couplings and diagnostic equipment you're already running. No adapters needed as long as your existing hardware matches that sizing and thread standard.

got a Stauff test point setup already. is this SMK-20-R1/4K-VD-W3 the kind that’ll hook up to the standard Stauff couplings and diagnostic gear?
Answer by: Customer Support on Feb 21, 2026, 8:02 AM
With the size 20 designation and the R1/4 threaded connection, it’s meant to match Stauff’s standard test point coupling system so you can connect common diagnostic tools like pressure gauges and data loggers at a measurement point.
