CRT NUBBIN
The CRT Nubbin was designed to protect both the CRT packer cup and the tubular connection when a Casing Running Tool is used. Damage can occur to the seal and thread profile of the connection if there is misalignment when inserting the CRT. Without a CRT Nubbin, damage can occur to the packer cup as it passes through the connection. The nubbin’s improved stab flank reduces interference when inserting the CRT.
