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. Seals are sold individually. Keep some in your toolbox and be ready for the unexpected!

Great fix to a nagging leak

By Kemper

Comments about SECO 7, AN 37 Degree Flare Seal:

Had a transmission cooler line going to the radiator with -6 AN fittings that I could not stop leaking. I had never used these before, but found that Pegasus Auto Racing is one of the few that carried these special Seco Flare Seals and ordered them. Easy to install, and they immediately fixed my leak. Order extras for future repairs.

Service and delivery comments:

Ordering is easy and fast from their website. My order was filled and shipped same day, and delivery was fast. Thank You Pegasus !
