In the previous version of API 17D there was a specification for a "Fluid Coupling (Pressure Balanced)" that stated that a Multiple Port Coupling could be made by repeating dimensions C and D which would give a port spacing of 1.37", unfortunately it also has TYP against dimensions B, C and D which I have seen interpreted as meaning dimension B should be repeated as well which would give a port spacing of 1.74".
Pleas can anyone tell me what the normally accepted port spacing would be for an API 17D dual port hot stab?
Thanks
