Saddles should be installed after pipe pressure testing is completed. 2. Use only on PVC pipe. 3. Make sure you have proper type and size of saddle for pipe. Reference pipe diameter range, tap size and identification located on each hinged saddle. 4. Clean pipe surface thoroughly. 5. DO NOT use Vaseline®, plumber's grease, or any other petroleum based product on seals or o-rings. 6. Mount saddle on pipe with outlet facing desired direction. 7. McDonald hinged saddles are NOT designed to bottom out. Tighten bolts to the following torques: 3/4" and 1" thread size outlets: •2", 2 1/2", 3" pipe - 4 - 5 FOOT-POUNDS. (approx. 4 to 5 lbs pull on a 12" wrench) •4", 6", 8" pipe - 5 - 6 FOOT-POUNDS. (approx. 5 to 6 lbs pull on a 12" wrench) 1 1/2" and 2" thread size outlets: •3", 4" pipe - 5 - 6 FOOT-POUNDS*. (approx. 5 to 6 lbs pull on a 12" wrench) •6", 8" pipe - 7 - 9 FOOT-POUNDS*. (approx. 7 to 9 lbs pull on a 12" wrench) *Be sure to alternate tightening of the 2 bolts to ensure even loading. 8. Overtightening can cause failure of saddle, bolt or hinge pin. 9. After the corporation stop has been installed, recheck saddle torque and tighten if necessary. 10. McDonald hinged saddles are designed to withstand water working pressure up to but not exceeding the working pressure rating of the pipe up to 200 PSIG maximum. Use only on a cold water service. 11. Saddle testing should be accomplished while services are exposed and prior to backfilling. 3210-308 3/22 1. Whenever possible, saddles should be installed after pipe pressure testing is completed. 2. Make sure you have proper type and size of saddle for pipe. Reference pipe diameter range, tap size and identification located on the top piece of each saddle. 3. Do not use on PVC pipe. 4. Clean pipe surface thoroughly. 5. DO NOT use Vaseline ®, plumber's grease, or any other petroleum based product on seals or o-rings. 6. Mount saddle on pipe with outlet facing desired direction. 7. Tighten nuts evenly to a torque of 45-55 FOOT POUNDS. 8. After the corporation stop has been installed, recheck saddle torque and tighten if necessary. 9. A.Y. McDonald single strap saddles are designed to withstand water working pressure up to, but not exceeding, the working pressure rating of the pipe. Use only on a cold water service. 10. Saddle testing should be accomplished while services are exposed and prior to backfilling. WARNING: Not for use in applications with frequent cyclic loading such as air blow off valves on water and sewer force mains. 3210-319 4/22 1. Saddles should be installed after pipe pressure testing is completed. 2. Use only on PVC pipe. Make sure you have proper type and size of saddle for pipe. Reference pipe diameter, tap size and identification located on each saddle. 3. Make sure saddle sealing surface on the pipe is clean, free of “nicks”, gouges, or other imperfections that could cause leakage. 4. DO NOT use Vaseline®, plumber's grease, or any othe petroleum based product on seals or o-rings. 5. Place saddle outlet and strap around pipe and attach together loosely using capscrews into tapped holes. Then rotate the saddle into desired position. 6. A.Y. McDonald saddles are NOT designed to bottom out. Alternating between each bolt, tighten to the following torques: For 3/4" and 1" thread size outlets: 2", 2 1/2", and 3" pipe - 4 - 5 FOOT-POUNDS. (approx. 4 to 5 Ibs. pull on 12" wrench) 4", 6", and 8" pipe - 5 - 6 FOOT-POUNDS. (approx. 5 to 6 Ibs. pull on 12" wrench) 10" and 12" pipe - 24 - 26 FOOT-POUNDS. (approx. 24 to 26 Ibs. pull on 12" wrench) FOR 1-1/2" AND 2" THREAD SIZE OUTLETS: 4" and 6" pipe - 13 - 15 FOOT-POUNDS. (approx. 13 to 15 Ibs. pull on 12" wrench) 8" pipe - 17 - 19 FOOT-POUNDS. (approx. 17 to 19 Ibs. pull on 12" wrench) 10" and 12" pipe - 24 - 26 FOOT-POUNDS. (approx. 24 to 26 Ibs. pull on 12" wrench) 7. Overtightening can cause failure of saddle or bolt. 8. After the corporation stop has been installed, recheck saddle torque and tighten if necessary. 9. McDonald saddles are designed to withstand water working pressure up to but not exceeding the working pressure rating of the pipe up to 200 PSIG maximum. Use only on a cold water service. 10. Saddle testing should be accomplished while services are exposed and prior to backfilling. 3210-327 4/22 1. Whenever possible, saddles should be installed after pipe pressure testing is completed. 2. Make sure the proper type and size saddle have been selected for the pipe. NOTE: Both 10" and 12" saddles are available with multiple strap and saddle top combinations. Make sure the pipe size lies in the ranges listed on the strap/saddle top combination. 3. Clean pipe surface thoroughly. 4. DO NOT use Vaseline®, plumber's grease, or any other petroleum based product on seals or o-rings. 5. Mount saddle on pipe with outlet facing desired direction. 6. Tighten nuts evenly to a torque of 30-35 FOOT POUNDS. 7. Overtightening can cause failure of the pipe and/or the saddle. 8. After the corporation stop has been installed, recheck saddle torque and tighten if necessary. 9. A.Y. McDonald stainless steel band saddles are designed to withstand water working pressure, up to but not exceeding, the working pressure rating of the pipe. Use only on a cold water service. 10. Saddle testing should be accomplished while services are exposed and prior to backfilling.
