Locking Couplings

Hole Products locking couplings are made from the highest quality alloy steel, providing superior reliability and longevity.

Our standard core barrel assemblies are offered with full hole locking couplings, providing maximum stability and wear resistance. Locking couplings are offered with or without tang.
 
Tang is a tab of steel on the pin end of the coupling that ensures the core barrel assembly head rotates with the rod string.
