SafeWay’s S40 Series is a general purpose, double shut-off
fluid transfer quick coupling available with either a
rugged ball valve or leak-free, high flow poppet valve.
The S40 was the first two-way (double acting) sleeve
quick coupling, introduced by SafeWay in 1969 as our
first product. The S40 Series is widely used wherever
the ease and convenience of one-hand connection or
disconnection is desired. It is original equipment on a
wide variety of agricultural and mobile equipment.
