One Hand Operation,

General Purpose Couplings

The S40 Series quick couplings are a double shut-off design, with the addition of a two-way (double acting) sleeve feature. Introduced by SafeWay in 1969, the two-way sleeve allows one-hand connect or disconnect when the coupling is clamp or bulkhead mounted. The S40 Series is interchangeable half-for-half with the Parker/Pioneer 4200 Series. This model has a 1/4″ body size, 1/4″ female pipe thread, and a ball valve.

• Two-way (double acting) sleeve allows one-hand connect or disconnect when the coupling is clamp or bulkhead mounted.

• Reliable and durable ball locking mechanism provides smooth operation time after time.

• Critical parts are hardened for long service life.

• Interchangeable half-for-half with Parker/Pioneer 4200 Series.

• Method of obtaining and presenting performance data conforms to ANSI (NFPA) T3.20.2.R2, Hydraulic fluid power – Quick action couplings – Test methods.
