Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers stainless steel clamps for securing SDR9 cross-linked polyethylene (PEX) tubing to metal insert and plastic insert fittings. All performance tests shall be performed on assemblies of fittings, clamps and PEX tubing. Clamps shall meet the material and dimensional requirements prescribed. The surfaces of the clamps shall be smooth and free of foreign material. Clamps shall be free of cracks, holes, corrosion, voids, foreign inclusions, or other defects that are visible to the unaided eye that have potential to affect the clamp integrity. Insert fittings shall be joined to PEX tubing by deforming and locking a stainless steel clamp around the outer circumference of the tubing, forcing the tubing material into annular spaces formed by the ribs on the fitting. The clamping procedure shall be as follows: slide the clamp onto the tubing, insert the ribbed end of the fitting into the end of the tubing until the tubing contacts the shoulder of the fitting or tube stop.
