The Progressive Chemical Injection Sub (CIS) was designed to be used with the Progressive Quarter-Turn Anchor and Progressive Safe Tensioning Tool as a system in deviated wells which make surface pipe manipulation difficult. Constructed from L-80 material for increased strength the CIS also has a wedge shaped guard to protect the connection of the capillary string to the CIS. The CIS comes in a regular version and a slimhole version for heavy weight casing.
