Amerex 11674 Downtube & Retainer Assembly for A411, A412, A413

Rebuilding a 20 lb aluminum dry chemical unit takes this downtube and retainer set. Amerex lists it for the A411, A412 and A413, and the retainer keeps the tube aligned in the valve so it clears the cylinder floor as designed. Ordering genuine part 11674 avoids the fit issues that come with aftermarket tubing.
