GROOVED COUPLINGS

Gasket Installation – Preliminary Steps –

1. INSPECT PIPE ENDS: For optimum sealing by the gasket, the exterior surface of the pipe ends must be free from any indentations, pro-jections, roll marks or other harmful surface defects such as loose paint, scale, dirt, chips, grease and rust.

2. CHECK GASKET: Verify the gasket supplied is correct for the intended service. Color code identifies gasket grade. Refer to page 36 for additional information on gaskets.

3. LUBRICATE GASKET: To help insert pipe smoothly and mount couplings smoothly without pinching, apply a thin layer of Shurjoint Lubricant to the sealing lips of the gasket and as well as to the exterior of the gasket. Other compatible lubricants may be used so long as they are not harmful to the gasket. System tempera-ture should also be considered when selecting a lubricant. See page 38 for details.
   Note: Lube-E gasket: Normally no lubricant is required when using a Lube-E gasket.

4. INSTALL GASKET: Install the gasket over one end of the pipe so that the pipe end is exposed. No part of the gasket should overhang this end of the pipe.

5. BRING THE MATING PIPE TOGETHER: Bring together and align the two pipe ends to be joined. Slide the gasket over the ends and center it between the grooves of the pipe to be joined. No part of the gasket should protrude into the groove of either pipe.

Please read these instructions carefully before installation .

1. Refer to page 50 for preliminary steps 1,2,3,4 & 5.
2. ASSEMBLE COUPLING: For a “swing-over” assembly loosely install one bolt and nut on one side of the coupling. For a standard assembly start with the two housings separated.
3. INSTALL COUPLING HALVES: For a “swing-over” installation, place one of the coupling halves around the bottom side of the gasket and swing over the other coupling half into position over the top side of the gasket. In tight areas where a swing-over is not possible, install the coupling halves one at a time. In both cases make sure the coupling keys are engaged in the grooves.
4. INSERT BOLT & NUT: Insert the remaining bolt and apply the nut hand-tight. Make sure that the oval neck of the bolt engages into the bolt hole of the housing.
5. TIGHTEN NUTS (For 1¼” to 12” Models Z07 and Z05 Couplings): Tighten nuts alter-nately and equally until the bolt pads meet and make metal-to-metal contact. Tighten nuts by another one-quarter to one-half turn to make sure the bolts and nuts are snug and secure. The use of a torque wrench is not required.
6. LARGE DIAMETER COUPLING: Large diameter couplings over 14” consist of three to four housing segments. To prepare installation, preassemble the segments loosely into two or three equal assemblies depending on sizes. Install those assemblies over the gasket in the same manner as described above.
7. TIGHTEN NUTS (For 14” to 24” Models Z07 & Z07N Couplings): Tighten nuts alternately and equally until the bolt pads meet and make metal-to-metal contact. Tighten nuts by another one-quarter to one-half turn to make sure the bolts and nuts are snug and secure. The use of a torque wrench is not required.

CAUTION

1. Uneven tightening of bolts and nuts may cause the gasket to be pinched, resulting in an immediate or delayed leak.
2. Never exceed torque stated in the table on page 34. Excessive tightening of nuts may cause a bolt or joint failure.

NOTE: As the coupling bolts are tightened, the angled bolt pads slide in opposite directions causing the coupling keys to tightly grip the pipe, while at the same time the pipe grooves are forced outward against the coupling keys. The bolt pads should always maintain metal-to-metal contact. Tighten nuts by another one-quarter to one-half turn to make sure the bolts and nuts are snug and secure. The use of a torque wrench is not required.
