Twist-On Oil Filler Tube

The Twist-On Oil Filler Tube by Mr. Gasket is a reliable engine component designed for vehicle owners who demand dependable oil system maintenance and easy access to the crankcase. This aftermarket filler tube replaces factory units that have become worn, corroded, or damaged, providing a straightforward solution for keeping your engine properly serviced. Whether you're performing routine oil changes or conducting engine diagnostics, a quality filler tube ensures secure sealing and hassle-free operation every time you add oil to your engine.

Engineered by Mr. Gasket, a respected name in engine gaskets and sealing components, this twist-on design delivers a secure, leak-free connection that eliminates frustrating spills during oil changes. The twist-on fitting mechanism allows one-handed installation and removal, reducing installation time and simplifying future service intervals. Constructed to withstand repeated use and temperature cycling common in engine bays, the tube maintains its structural integrity and seal performance over extended ownership, making it a cost-effective replacement for any worn original equipment filler tube.

Mechanics and DIY enthusiasts benefit most from this replacement part when addressing oil leaks near the valve cover area or when the factory cap no longer seals properly. Installation is straightforward—simply twist off the old tube and hand-thread the new Mr. Gasket unit onto the rocker cover opening, tightening by hand to ensure a solid connection without over-torquing. Compatibility varies by vehicle year, make, and engine type, so verify your specific fitment before purchase to ensure correct seating on your engine's oil cap mounting point.
