Royal Purple manufactures only one type of oil filter – the super-premium Extended Life Oil Filter, designed to perform as the best oil filter available. This filter is engineered to match superior particle removal with optimised flow for maximum engine protection and filter life. Built smarter and stronger, Royal Purple synthetic oil filters continuously outperform in the toughest conditions.
DESIGN AND CONSTRUCTION ADVANTAGES
SHELL
Each Royal Purple oil filter features thicker shell material for extra strength and extra security against puncture from road debris.
METAL END-CAPS
Provide each oil filter with a positive seal for filter element assembly.
CENTER TUBE
Designed to prevent filter element collapse.
FILTER ELEMENT
100% screen-backed synthetic media provides superior filtration while keeping flow restriction low.
BY-PASS VALVE
Engineered to ensure oil flow in situations of excessive filter element flow restriction.
STEEL BACKPLATE
Heavy-gauge steel backplate through each filter for higher burst strength.
GASKET
Premium nitrile rubber with special lubricity compound reduces torque during installation and removal.
SILICONE ANTI-DRAIN BACK VALVE
Prevents dry starts by eliminating oil drain-back during shutdown. The anti-drain back valve is made of silicone, which outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures.
