Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Connect drinking water lines with ease—these one-piece fittings have a built-in sleeve that crimps onto tubing for a leak-tight connection that doesn’t require heat or soldering. These fittings meet NSF/ANSI 61 for drinking water systems and are compatible with Viega PEX tubing.
