O-ring Seal Sub

This is a completion accessory that facilitates completion and gravel pack operations by providing pressure and fluid sealing at selected point in completion assembly.

O-ring seal sub is a simple short tubing sub with elastomeric sealing for the polished stinger used on the internal string. During sand control operations, these accessories direct fluid flow to assist with effective fluid movement.
They can be placed at the bottom of the screen assembly.

This ensures treatment fluids are pumped all the way to the end or bottom of the production screens to promote complete screen covering with gravel.
