Annulus Lubrication Filling Tool (ALF)
Unity’s Annulus Lubrication Filling (ALF) tool has been developed to allow the live tubing and casing annuli on a well to be simultaneously filled while providing a conduit for any trapped air to be expelled.
It is available in 5,000 psi and 10,000 psi specifications, with a quick union connection for fast and easy deployment. This tool is manufactured in accordance with API 6A, PSL 3 and PR1 requirements.
