SECO 7 Seals can solve the most persistent leaks in your AN plumbing. They are especially indispensable when connecting flared tubing to male AN fittings with AN tube nuts and tube sleeves. They can also compensate for misaligned tubing and imperfect flares.

Originally developed for NASA, the soft annealed 37° conical seals act as a crush washer on the male AN flare. They help to ensure reliable, leak-free seals while preventing damage to the tubing or the AN fitting. They can even help rescue fittings that have been damaged at the seat from debris, overtightening, or manufacturing irregularities.

Each size is available in Aluminum or Copper. Use aluminum seals with aluminum tubing and fittings; use copper seals with steel tubing and fittings. (Use aluminum seals with aluminum-to-steel joints.) Seals are sold individually. Keep some in your toolbox and be ready for the unexpected!

"A dash three size conical seal won a championship race for us. I carry a full range of the things in my toolbox and consider anyone who knows about them and does not carry them to be foolish."
-- Carroll Smith, Nuts, Bolts, Fasteners, and Plumbing Handbook

Fixed my leak

By Patrick

from Portsmouth, VA

Comments about SECO 7, AN 37 Degree Flare Seal:

I have an aftermarket clutch master cylinder in my car. The connection from the reservoir to the master is a -8AN connection, with aluminum fittings. There is no pressure here, but I couldn't get it to stop weeping brake fluid. I installed one of these copper seals and it leaked worse until I really cranked down on it. It's in a tight place, so I had to use some extensions and a flare nut crowfoot socket. No drips now. I might order an assortment of these just to keep on hand, as they're really handy and not locally available.

Service and delivery comments:

Shipping was fast and inexpensive.

It worked!

By Fast402

Verified Buyer

Comments about SECO 7, AN 37 Degree Flare Seal:

I replaced three hose ends before I realized I must have damaged the male fitting coming out of my fuel pump hanger. Big problem! So I went searching and bought some copper flare seals from Pegasus. My leak is fixed and I am saved a really nasty job to replace the damaged part.

Service and delivery comments:

Great service and prompt delivery!

Use on all AN fittings

By PbFut

from Murrieta, CA

Verified Buyer

Comments about SECO 7, AN 37 Degree Flare Seal:

That extra added protection. Formed for AN bungs, order a few extra. They come in handy. A little pricey for what they are, still worth it for how they perform.
