The 91 Series is a variation of the 20 Series Couplers. The valve has been shortened in respect that the plug seals before the Coupler valve opens. In spite of the short valve, the well-proven, single hand operation is retained as the ball-lock is replaced by a pin-lock. This extends the external diameter of the sleeve from 10 to 13 mm. This series is also available without a valve in a Straight-Thru design. For Straight-Thru Couplers, please change the part number from 21KA to 21KF when ordering.
