Note 2: We are constantly upgrading our products and while we try to keep the websites up to date it is possible more current specifications may be on a quote or confirming order. Note 1: Mechanical and Molded Rubber Plugs are generally used for testing because fabricated Multi-Flex ® style plugs may allow some seepage unless customized for a positive seal. Please review our Warranty, Terms and Conditions. Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Continue with appropriate operating procedures.Unscrew the chain connector and switch the link around if necessary. Insure you have the appropriate link set-up before using. Each link can do at least two sizes of shafts. The links are stamped with the shaft sizes they can accommodate. Safety Gags 8" and larger are equipped with two chain and link assemblies. Prior to pressurizing the system, slip the link over the shaft end. ![]() Follow appropriate operating procedures for the plugs being utilized, and install plugs per recommended torque values using a calibrated torque wrench. Tighten bolts to insure slippage will not occur.Safety Gags are to be installed with some slack so that movement of the shaft is not prohibited as pressure increases during testing. Install Safety Gag pipe clamp onto pipe being tested.Should movement be noted, the test should be stopped and all pressure released immediately. The amount of slack in the chain as well as the position of the installed plug should be observed from a safe distance to insure no appreciable movement of the plug has occurred. Installing the Safety Gag with a tight chain may limit or prevent the small movement of the test plug shaft as pressure is increasing, and subsequently limit or prevent the self-sealing and self-gripping feature of our test plugs. The extra squeeze of the seal and gripper caused by the test pressure can be detected as minor movement of the shaft. The 147 Series Test Plugs are designed to be self-sealing and self-gripping, which facilitate both the seal and the gripper to become tighter as pressure increases. Please refer to the appropriate operating procedures for the test plug being utilized. Warning: These are general instructions only. They are made with painted carbon steel with plated chain. Any credit allowed willīe against future purchases after a 20% handling and restocking charge.These Safety Gags clamp to the outside diameter of standard pipe sizes for use with mechanical test plugs.
