High Pressure, Thread to Connect Quick Couplings |
The S30 Series is a special purpose, double
shut-off fluid transfer quick coupling that provides
significantly less pressure drop than couplings of
the same type produced by other manufacturers.
A threaded sleeve locking mechanism mates the
coupling halves and allows connection under
pressure up to a maximum of 1,000 psi. Our
heavy-duty poppet valving, while fully interchangeable
with ball check models (including older
SafeWay product), eliminates low pressure leakage.
The S30 is designed for extreme high pressure
applications including portable hydraulic tools,
wire pullers, and frame straightening equipment.

|
|
|
SafeWay began a running change from zinc and
yellow chromate plating (gold appearance) to ROHS
compliant plating (silver appearance) in 2007. |
|
Designed for extreme high pressure applications such as
portable hydraulic rams, wire pullers, etc. |
|
Rated working pressure of 10,000 psi in all sizes. Threaded
sleeve locking mechanism mates coupling halves. Couplings can
be connected under pressure up to 1,000 psi. |
|
Heavy-duty steel dust caps and dust plugs are available. |
|
Method of obtaining and presenting performance data
conforms to ANSI/(NFPA)T3.20.2.R2, Hydraulic fluid power
- Quick-action couplings - Test methods. |
