I'll take the 4- 416 kits. I'm pretty sure that's what my caps are, it's an "M" model as well and my caps look like your's in the pictures.

Fluorosilicone O-rings arrive today and we will be packing them up for shipment via USPS tonight. If you have paid, they will ship tomorrow. If you have not paid then they will not ship! I still have product available and I am in the process of placing another order for additional rings. I will be doing D'Shannon tip tanks but I have not finalized the products for the kits. Expect pricing to be comparable to what you see here. Stay tuned for additional details.

The problem with fluorosilicone O-rings are that they are expensive to manufacturer and no-one maintains a ready stock of them. The next order will probably arrive in January. With a 4-5 week lead time, it is difficult to stock this product when you get close to selling whatever you order before it arrives!

As for the lifetime of a fluorosilicone o-ring, I have yet to definitively figure that out. I have heard folks say they have had rings on their caps in excess of 19 years! My advice is to inspect them for wear and damage every time you fuel up your bird and replace as necessary. I am in a sense though, working myself out of business as the fleet equips with these rings. They are a superior product to rubber nitrate rings.

If you're interested in kits, reply to this thread or fire off a PM to me!

Hello James,

I just saw your post today. If you have any #531 kits left I would like two #531 kits please. Let me know how to pay.

Thanks,
Joe

Two sets for the Gabb style, please!

So we did not anticipate UPS delivering all of this around 9 PM this evening. We will not be able to ship tomorrow as promised. Saturday will be the day and it will come via USPS. I am still taking orders. Some product may be able to immediately ship if you are paid up, otherwise you will have to wait until the next batch arrives.

Thanks for the update. I am also interested in the seals for the Osborne tip tanks. If the D'Shannon tip tank seals will work put me down for a set. Thanks again.

Are these O rings different than the first batch that was sent out?

No. They are the same.

Orders are ready and will ship tomorrow via USPS. I have stock for all products and they will ship next business day until I'm out. PM for payment details and desired order. Another order is on the way but it will be January before they arrive.

O-rings have shipped! This is a great way to prevent fuel contamination. Replace your obsolete or damaged rings today!

Received! Looks great.

Thanks,
Greg
