* ISO 7241-1 Series B does not include 1-1/4 inch body size couplings; therefore, Series 10HK is not covered by this standard
A=Overall Length, B=Maximum Diameter
C=Overall Length, D=Maximum Diameter, E=Exposed Length when Connected
To obtain connected length of coupling, add dimensions A (Fig. 1) and E (Fig. 2) together.
To obtain connected length of coupling, add dimensions A (Fig. 3) and E (Fig. 4) together.
