FINALLY DISCONTINUED - USE SPLIT NUT OF SAME I.D.
- For heater tubes with 2 1/4 inch outside diameter.
- Sold in a pair as nut and retainer ring to repair/replace cracked or broken pieces.
- TIP: Nut installs first, then retainer ring is split open and forced over tube flange to allow nut to pull against flange. recessed notch on ring faces nut.
- NOTE: Not a replacement for 'split-nuts'.
