The seal moves down the angled surface to accomodate the different sizes of pipe. The inner seal holds the pressure (300 PSI), while the out- er seal keeps dirt and contaminants out of the fitting. Seals are made of NSF approved EPDM. Pipes are inserted to the indicator mark- ings on the body. Size ranges are clearly marked in inches and millimeters on the outside of the nut Cambridge Coupling Rated for 300 PSIG Additional Information - Every component is made of NSF-61 approved materials, and meets the low lead guidelines regardless of whether it is in contact with water - Wide wrench flats make it easy to use common everyday tools to tighten the connections - The coupling body and nuts are made of quality waterworks C89833 Pipe Material Insert 1/2” 5/8” 3/4” 1” 1 1/4” 1 1/2” 2” Copper (CTS) Not Required U2 U2, U3 U2, U3 U3, U4 U4, U5 U5, U6 U7 Polybutylene, Polyethylene, PET, PEX SDR9 (CTS) Series 86 U2 U2, U3 U2, U3 U3, U4 U4, U5 U5, U6 U7 Galvanized Steel (IPS) Not Required U2, U3 - U3, U4 U4, U5 U5, U6 U6 U7 Polyethylene SDR9, SDR11, SDR17 (IPS) Series 88, 89, 94 - - U3, U4 U4, U5 U5, U6 U6 U7 PVC (IPS) Not Required U2, U3 - U3, U4 U4, U5 U5, U6 U6 U7 Polybutylene, Polyethylene PET, PEX, SIDR7 (PE) Series 87 U2, U3 - U3, U4 U4, U5 U6 U7 N/A Lead Pipe - Strong (S or A) Not Required U2, U3 U3, U4 U4 U5 U6 U7 N/A Lead Pipe - Extra Strong (XS or AA) Not Required U2, U3 U3, U4 U4 U5 U6 U7 N/A Lead Pipe - Double Extra Strong (XXS or AAA) Not Required U3 U4 U4, U5 U5 U6 U7 N/A Nominal Pipe Size Installation Instructions 3. INSERT THE PIPE: Insert the pipe to the depth noted. (You may wish to tighten the nut to make the rubber close to the pipe diameter before insertion. 2. INSERTION LENGTH: Put the fitting beside the pipe and note the length of the pipe to be inserted (use your thumb or marker as a guide.) 4. TIGHTEN THE NUT: Using standard wrench- es, tighten the nut to seal and grip the pipe. 5. COMPLETION: Continue to tighten until the nut will not move with reasonable force. 1. CUT PIPE TO LENGTH: Make a clean cut, square to the pipe using an appropriate cutter (roll cutter or shears are preferred.) Service Line Fittings Engineering Service Line Fittings
