The advanced straight tee filter pack is used on the bottom outlet of oil tanks. It consists of a 1″ shut off valve which is fitted to the tank as a primary component, thus enabling the tank supply to be disabled should anything happen to the filter. The filters are fitted as a secondary component after the valve with a tea piece in between the valve and filters. The components used are all made in the UK with high precision tooling. Each kit is supplied with 1 roll of PTFE tape.Click here for: Atlantis Advanced Straight Tee Filter Pack Detail SheetClick here to watch video : Advanced Straight Tee Filter Pack Key Features: Made in the UK Biofuel Compliant Future Proof Fitted with Viton Seals Throughout Machined from one piece Aluminium billet.
