MaintenanceRecommendationsProprietary and Confidential23

Best Practices No pipe dope No Teflon tape Tighten couplings and covers byhand, then “snug” with a wrench Fixed smooth-jawed wrench Avoid compression wrenches“Snug” – don’t over tighten Carry 100% silicone grease Clean threads with a brass bristlebrush Wet the gaskets before installing Clean with soap and water onlyClean with soap and waterProprietary and ConfidentialUse Genuine Sloan Parts24
