S-Type Keg Coupler - Stainless Steel/Alloy

S-Tye Keg Couplers are almost identical to D-Type Couplers except that S-type has a much longer piston to engage the keg spear.

Within Australia, S-Type variety kegs are commonly associated with Asahi, Heineken and Hofbrau (HB) kegs

Keg King S-Type Couplers come equipped with:

5/8" Male Beer and Gas threads on the coupler body
x2 6mm Barbs for gas and liquid line connections
1 x - Non-Return Ball or Torpedo check piece (Non-Return Liquid)
1 x - Gas Duck Bill valve (Non-Return Valve for Gas)

About the Gas Duck Bill Valve:
The duck bill valve is a washer as well as a non-return check piece.
It is optional, you do not have to use the non-return check pieces for gas or liquid.
If removing the Duck Bill Valve, ensure you use a 5/8 Silicone washer to seal the 5/8 nut onto the threaded gas input on your coupler. 

Other beverage brands that use S-Type variety kegs may include:

Amstel

Newcastle

Pilsner Urquell
