The Most Accurate Hardtop Seal Kits Ever Offered

If your Austin Healey hardtop is letting in wind, water or annoying rattles, these two all-in-one perimeter seal kits do the job in a single afternoon—no scavenger hunt for rare profiles or obsolete trim pieces. Whether you're dealing with perished rubber, mismatched sections from previous repairs, or just want to restore that satisfying factory fit and finish, these kits provide a practical and accurate solution.

These are not approximation kits. These are the most accurate perimeter seal kits ever made available for Big Healeys—faithfully re-created from original samples and developed with reference support from Roger Moment. Every rubber seal profile in these kits follows the original equipment specification to the millimetre, using high-quality EPDM that mirrors the factory finish and fit.

The only difference? The steel-core woven cotton finishing strip is now supplied in a light grey rather than beige. Visually, it blends in neatly with the hardtop and avoids the yellowing and age-staining issues that came with the original colour.

Choose the right kit for your model:

HDT140 – BN6 & BN7 perimeter seals
HDT144 – BN4 & BT7 perimeter seals

Why these are the best-fit seals your Healey will ever wear:

O.E.-matched EPDM rubber profiles – recreated from original factory samples
Colour-coded lengths – clear, stress-free installation without guesswork
Steel-core woven edge trim – now in light grey for cleaner finish and longer-lasting appearance
Photo-rich instructions – developed in collaboration with Roger Moment
Eliminates water ingress and wind noise – seals the cabin and restores roof alignment

How These Kits Give You a Better-Sealed Hardtop

When dried-out or mismatched seals let moisture past the header rail, it’s not just an annoyance: trapped water can corrode your check-straps, rust the bodywork and lead to squeaks that ruin a tranquil drive. These kits recreate every outer seal exactly as Austin-Healey intended—no compromises.

Fit It Once—Enjoy It Every Drive

Strip back the old seals and thoroughly clean the flange to give the new rubber a smooth, clean surface to bond against.
Identify and align each colour-coded seal using the supplied diagrams—no second-guessing or trial and error.
Press and position the EPDM into place, using the pre-drilled holes and original flanges to maintain factory geometry.
Finish the edge with the light grey woven cloth strip—steel-cored for durability, flexible for a neat contour around the roofline.
Step back and enjoy a proper seal: no whistles, no drips, just a tight, clean finish that holds the line beautifully.

No specialist tools or workshop space required—just trim tools, a bit of patience, and a decent brew. Whether you're restoring in your garage or fitting in a pro workshop, this is a job you can get right the first time.

Frequently Asked Questions

Will the light-grey cloth strip look out of place?

Not in the slightest. It blends into the hardtop visually, especially from eye level. Unlike the original beige trim, the light grey won’t yellow or draw attention to itself over time.

Do I need to supply my own adhesive?

Yes—this kit doesn’t include adhesive. We recommend using a light, non-setting black sealant. Most garages and home restorers already have something suitable to hand.

How long should the installation take?

That depends on your tools, workspace and experience, but with the included diagrams and photo guide, most owners find the process straightforward and manageable in a single session.

Can I reuse my original clips or fasteners?

In many cases, yes—if they’re still straight and corrosion-free. But if any are bent, brittle or rusted, now’s the time to swap them for fresh ones and avoid future headaches.
