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
