COUPLER CLOSURE TYPE             

4 PITCH

A second type of closure supplied incorporates a 4 pitch acme, DOUBLE-START thread, again with "BLUNT-START" and "RELIEVED THREAD"  features. 

This design also includes the same AXI-NUT action found on our 8-pitch coupler,
making the coupling action more rapid then other brands.
