- 1-piece Retainer Ring that won\u2019t fall off the fitting during installation.<\/li>\n
- Convenient, hand-tightening followed by 1\/4 to 1\/2 turn with a wrench to seal the fitting – no more cumbersome torqueing with wrenches on ladders, in crawl spaces, or in other confined spaces.<\/li>\n
- Dual-size, inside-tapped fittings – ask any installer how handy this feature can be.<\/li>\n
- Annealed tube that allows the tubing to bend and stay bent.<\/li>\n

To achieve the proper Torque without a torque
wrench, first tighten the fitting adapter to the nut
until resistance to hand tightening is so that you can
no longer continue. Then, using a crescent wrench,
tighten to 1\/4 to 1\/2 turn.<\/p>\nCAUTION: DO NOT OVER TIGHTEN!<\/h3>\n<\/div>\n<\/div>\n\n\n\n
