BT7 furflex/rubber door seals

When I restored my car about 10 years ago (cannot believe that it has been that long!) everyone was complaining about the quality of the door seals. MacGregor in Canada started manufacturing and selling a superior product that I used on my car. I was quite pleased with the quality. However, after 10 years the rubber is beginning to crack in a few places and I would like to replace them. Do I recall correctly that Moss or another U.S. vendor now sells the MacGregor product? Thanks for any helpful advice.

Years ago I too went through the door seal fiasco, if you want correct door seals go to Macgregor.

I worked sometime introducing his product to our local Healey enthusiasts.

Hi Lin
Rubber can be easy saved ( if don't seriously damaged) with a gentle touch of Vaseline application

Here's a basic question about cutting furflex: what is the best way to cut these to size and keeping clean cuts. I ordered a set of Britflex / Furflex from MMs only to find them too short with the end sections frayed and splayed. In a word, unserviceable.

This time I'm buying from another supplier. Any suggestions are welcomed. GONZO

As I recall the advantage to Martin's product when he introduced it was that it would stay clamped on whereas the metal in the seals that Moss and others sold was too flexible and eventually fell off, etc. Is that still the case?

BCF policy is that you address vendor problems with the vendor. Doesn't sound like you've gone back to Martin to let him know that the two lengths of his product, Bristleflex, were cut too short.

If the pieces you received were too short, as you state, then why would you come here to ask how to cut them cleanly? No matter how many times or how cleanly you cut them, they'll still be too short. Therefore your question looks like nothing more than a premise to vendor-bash.

Let's get this back on track. Deal with the vendor to resolve the matter. If you're determined to use a different product and looking for a recommendation for one, there's no need to recount your frustration with the previous vendor. Thanks.

I'd appreciate someone answering my question: Is Martin MacGregor's product superior in the manner that it grasps and holds onto the sheet metal as was once the case or are the products from the various vendors pretty much the same?

i have used it on the last three healeys that i owned. i have no experience with other vendors but it has never come loose once installed. limited experience but really grips well. he makes his own product and I believe that he does sell to other vendors.

The Macgregor product is far superior in the way it grips and stays gripped to the standing seam .
It also seals better as it has a larger sealing bulb section that squishes when you close the door .
I wouldn’t use anything else .
The only issue I have with it is the rubber end caps dont exactly match the profile of the seal . This may have been corrected since I last bought some ???
As for cutting it I found sheet metal cutters worked the best . Cut it slightly long by 1/4” then snip away till you reach the correct length . Make sure your cutters are really sharp .

MacGregor's product is called Bristleflex. I installed it >10 years ago when it first came out and was very happy with the results. The metal component is steel; the Furflex was aluminum and wouldn't stay attached to the metal edges.

Addendum: According to the Moss catalog, Furflex now has a steel structure.

The bulb on my driver's side door has split and I will also be replacing.

Addendum: when MacGregor introduced Bristleflex, there were two types of trim available: 1) steel structure but the bulb was too big; 2) weak aluminum structure with correct bulb diameter. Bristleflex had steel with the correct smaller bulb diameter.

I have not tried Vaseline to revive rubber seals, but a 50/50 mix of white spirit and glycerine works very well on tired rubber seals. If you want to go more advanced, start with a mix of 80 white spirit/20 glycerine and rub it in well, continue with gradually more glycerine/less white spirit and do it over a period of several days.

I'll try practice cuts before committing to final cuts to avoid splayed and frayed ends.

I can't explain why I'm so O.C about this particular trim piece and wanting it perfect. Perhaps its the fact that BJ-7s and 8s don't have aluminum / chrome finishing pieces like the earlier models and as a result, look fussy and "unfinished". Thanks for all the suggestions, GONZO.

There is a small chrome clip that fits at the end of the furflex behind the doors: https://mossmotors.com/clip-door-seal-end?assoc=8277
