Rapid Installation Pivot-Bolt (GRIP) Rigid Coupling Figure 740 Rapid Installation Pivot-Bolt (GRIP) Rigid Couplings are a proven, dependable, and more efficient method of joining pipe than standard couplings. Simply push the gasket onto the pipe, swing the coupling body over the gasket, and tighten only one bolt. In comparison with other installationready couplings, the Figure 740 GRIP Coupling allows clear visual confirmation that the gasket is properly seated on the gasket sealing surfaces. The Figure 740 GRIP Coupling is capable of pressures up to 750 psi (51.7 bar). The Fig. 740 GRIP Coupling saves installation time in two ways: • Only one bolt on the coupling requires tightening. For Listings/Approval Details and Limitations, visit our website at www.anvilintl.com or contact an Anvil® Sales Representative.
• The gasket is specially designed for an easy push-on installation. Preparation of the coupling for installation is also quicker. The nuts do not require un-torquing to remove the gasket as do the nuts used in standard rigid couplings.
The bolt end in the Figure 740 GRIP Coupling is staked to prevent inadvertent misplacement or loss of nuts during installation.

INSPECT PIPE AND DISASSEMBLE COUPLING
Verify that the coupling and gasket grade are correct for the application.
Inspect exterior groove and ends of the pipe to verify all burrs, loose debris, dirt, chips, paint and any other foreign material is removed. Ensure pipe end sealing surfaces are free of sharp edges, projections, indentations, and/or other defects. Disassemble coupling by loosening the nut on the Coupling Bolt only. Loosen nut to the end of the bolt and swing out of slotted hole. Remove the gasket. NOTICE: Do not loosen or adjust the nuts on the Pivot Bolt. The Pivot Bolt assembly is factory-preset for optimal performance. In the unlikely event that the nuts have become loosened, tighten the nuts on the Pivot Bolt to a minimum torque of 10 ft.-lbs.

4
INSTALL HOUSING
Swing the coupling housing over the gasket. Verify that the housings are over the gasket and that the housing keys are fully engaged into the grooves.
5
INSTALL BOLT
Slide the Coupling Bolt and nut into the housing and tighten the nut until finger tight. Verify that the bolt head is fully recessed in the housing and the nut is recessed into the counter-bore around the slot.
LUBRICATE GASKET
Apply a thin layer of lubricant to the gasket. Be sure to include the sealing edges as well as the outer surfaces. To prevent deterioration of the gasket material, a petroleum lubricant should never be used on Grade EHT gaskets. For assembly below 40°F (4°C), a petroleum-free silicone lubricant is recommended be used to prevent freezing of the lubricant.
NSF Requirement: In order to retain the NSF 61 certification, an NSF 61 certified lubricant must be used for the intended service.
3
INSTALL GASKET
Install the gasket by pushing it over the pipe until the center stop of the gasket is in contact with the end of the pipe. Slide the other pipe end into the gasket ensuring it makes contact with the center leg of the gasket. Both pipe ends should be aligned vertically and horizontally. The gasket should now appear evenly spaced between the two grooves and the outside of the gasket should be parallel with the pipe.

NOTICE: Figure 740 GRIP Coupling has an intended gap of up to 1/16 of an inch on the Coupling Bolt side to allow for positive rigid gripping onto the pipe. The patented tongue and groove design provides protection to the back of the gasket during installation. For recommended bolt torques, refer to above table..
