Bisrollnaa Exhaust Gasket Seal Installer Tool for Harley-Davidson – Black Anodized 6061 Aluminum, Fits Evo/Twin Cam/XL

Bisrollnaa's Exhaust Gasket Seal Installer Tool aligns and seats Harley-Davidson exhaust gaskets reliably, preventing leaks and ensuring an exact fit every time.

If you service or modify Harley-Davidson motorcycles—Evo Big Twin, Twin Cam, XL models, or air-cooled Buell bikes—accurate gasket placement is essential to avoid exhaust leaks and rework. This installer was engineered to position both tapered and flat exhaust gaskets (including H-D No. 65324-83B and Screamin' Eagle No. 17048-98) squarely into the exhaust port and cylinder head so the gasket compresses evenly and forms a consistent seal.

How does this tool improve gasket installation speed and accuracy?

The tool provides a guided surface that holds the gasket concentric to the port while you start the exhaust pipe, removing guesswork and misalignment. It reduces fumbling with small seals and cuts the time spent correcting pinched or crushed gaskets.

• Guided seating prevents off-center placement and warping.
• Works with tapered and flat gasket profiles used on Harleys.
• Simplifies one-person installs—no assistant required.

Will this fit my Harley model and specific gasket types?

The Bisrollnaa installer is sized for common Harley gasket styles and model years: tapered exhaust pipe gaskets like H-D 65324-83B and flat Screamin' Eagle seals such as 17048-98. It supports Evo Big Twin and Twin Cam models from 1984 onward and XL and air-cooled Buell models from 1986 onward.

• Compatible with Evo Big Twin and Twin Cam (1984–present).
• Fits XL and air-cooled Buell models (1986–present).
• Designed for H-D tapered and flat performance seal kits.

What is the tool made of and how durable is it?

Manufactured from high-grade 6061 aluminum alloy, the installer is sand-blasted and finished with black anodizing for corrosion resistance and long-term durability. The machined geometry resists deformation during normal workshop use and stays true over repeated installations.

• 6061 aluminum offers excellent strength-to-weight balance.
• Sand-blasted surface ensures consistent handling and fit.
• Black anodized coating protects against wear and corrosion.

How do I use the installer in a typical exhaust rebuild or upgrade?

Place the tool over the exhaust port, center the gasket onto the guide, and gently press or slide the exhaust pipe into position—letting the installer hold the gasket in place. Once the gasket is seated and the pipe begins threading or sliding home, remove the tool and complete the final tightening to factory specs.

• Position tool over port, center the gasket on the guide.
• Start exhaust pipe while tool maintains gasket alignment.
• Remove tool once gasket is held and finish torqueing fasteners.

Who this is for: This installer is built for DIY enthusiasts, professional motorcycle techs, and shops that frequently service or upgrade Harley-Davidson exhausts. If you want repeatable, leak-free gasket seating for tapered or flat Harley gaskets—especially when working alone—this tool reduces installation errors and saves time on Evo Big Twin, Twin Cam, XL, and compatible Buell models.
