Check gasket color code to be certain it is recommended for the service intended. For services not listed, contact an Anvil Representative for recommendation. This lubricant is waterproof, thereby eliminating water wash-out and it will not dry out in the absence of water.

It is not to be used with Silicone gaskets. The temperature change will also force the gasket to slightly re-position itself. This will cause pipe end sealing surfaces, with small cuts or damage, to become more susceptible to leakage.

Gruvlok Xtreme Lubricant will maintain its lubricating properties at lower temperatures allowing a properly lubricated pipe end and gasket assembly to reposition itself during temperature cycles. Lubrication on the inside of the gasket is easily accomplished by turning the gasket Information inside out and applying the lubricant. Gruvlok Xtreme Lubricant will maintain its lubricating properties at higher temperatures, allowing a properly lubricated pipe end and gasket assembly to re-position itself during temperature cycles.

Lubrication of the pipe end and gasket will help the gasket to adjust into the proper sealing position during temperature cycles. This is particularly important at higher temperatures where oxidizing agents in the piping system become more aggressive.

However, gasket chemical compatibility must still be considered. It is sanctioned by the FDA under C. It is NSF approved for use with potable water. The lubricant is made from a water emulsion that is non-toxic, it will not impart taste or odor, and does not support bacterial growth. It is water-soluble. The quick drying quality of the lubricant eliminates lubricant drips caused by over lubrication.

If necessary, reapply lubricant prior to assembly. Do not thin or mix with solvents. Under torquing the bolts may result in lower pressure retention capabilities, lower bend load capabilities, joint leakage and pipe joint separation.

Data Installation Contents Gruvlok Table of To create a Gruvlok pipe joint, all pipe must be prepared to receive Gruvlok coupling or other Gruvlok pipe system components. The required pipe preparation may be grooving or cleaning the pipe ends, or cutting a hole in the pipe wall. For grooved-end joints, pipe may be grooved by either of two methods; cut or roll grooving. Branch outlet connections require a properly sized and correctly located hole to be cut into the pipe.

Sock-it connections require cleaning of the pipe end. Gruvlok plain-end pipe couplings require that the pipe be free of burrs and other sharp projections which could damage the Gruvlok gasket; grooving is not required.

Gruvlok roll grooving machines produce a groove to proper dimensional tolerances, concentric with the pipe O. Pipe and Gruvlok hole cutting tools properly center holes for correct assembly of Gruvlok branch outlet components. Weld Fitting and Cut-Grooving: Cut grooving is intended for use with standard and heavier wall pipe. Cut grooving produces a groove in the pipe wall by removing metal from the pipe O. The groove removes less Cut Grooving than one half of the pipe wall and does not cut as deeply into the pipe wall as do standard pipe Bolt threads.

Thread Cut Groove vs. Information Roll-Grooving: Roll grooving does not remove metal. Instead, metal is displaced while a groove is formed into the outer surface of the pipe wall.

Movement is possible in the Gruvlok coupling due to two factors: 1 designed-in clearance between the key of the coupling and the groove diameter and groove width, and 2 the gap between pipe ends joined by the coupling. The values account for pipe, groove, and coupling tolerances.

Maximum Oper. Thus, the number of couplings is determined as follows: No. The Gruvlok coupling will not allow for both maximum linear and maximum angular movement simultaneously.

In systems where both are expected, additional joints may be required. Gruvlok For Expansion In the example above, two couplings were added to account for thermal expansion and the other couplings accommodate only the misalignment. The additional stress from the combined movement is therefore relieved. However, Gruvlok Couplings should never be used as a continuous swivel joint. For pipe rotation, the system must be shut down and internal pressure relieved.

The pipe may then be rotated one-quarter turn, the couplings retightened, and service resumed. If performed on a regular basis, pipe rotation will evenly distribute wear over the entire inner surface of the pipe.

Buried Pipe Systems Pitched drainage systems, buried pipe systems where pipe laying conditions are subject to settlement, and exposed pipe systems laid on rough ground are but a few of the many types of pipe installations that present conditions where the functional capability of the Gruvlok coupling are useful.

Petroleum based lubricants are incompatible with EPDM and will impair serviceability of the unit. Thread Make-up and Installation A For use in systems installed in accordance with all applicable standards or codes. Compare number of threads counted to the number of required fully developed threads as shown in the thread chart located on the back of this sheet.

If thread count is correct, proceed with installation Step C , if thread count does not match, check nipple or sprinkler for proper thread gage measurement and discard if not to ANSI B1. D If either of the above fails to allow the sprinkler or nipple to make-up to a minimum of full threads, do not over tighten.

One advantage of cutting the hole after welding is that the pipe is left intact during welding thereby reducing shrinkage and possible distortion. If holes are cut prior to welding, as some codes require, then the following hole sizes are recommended. Every effort must be made to avoid welding too hot or overheating both the pipe and the Tee-Let.

Excessive heat may cause the wrench tight threads those in the bottom of the Tee-Let near the weld zone to distort while also causing the branch pipe to bend. It should be noted that Merit Tee-Lets have been subjected to exhaustive testing and evaluation, and only negligibly distort when subjected to excessive heat. The threads, on the other hand, may not return to their gauged form after cooling if excessive heat causes them to expand. Co2 - Deeper penetration, faster welding, low cost.

Merit assumes no liability for any consequential damages resulting from the improper use of its Tee-Let Welding Outlet Fittings, nor for any recommendations made with respect to installation procedures.
