ASSEMBLY INSTRUCTIONS

TYTON AND FASTITE PUSH-ON JOINTS

THE PROCEDURES DESCRIBED BELOW SHOULD BE FOLLOWED TO ASSURE PROPER JOINT ASSEMBLY. SUPPLEMENTAL INFORMATION IS COVERED IN THE ATLANTIC STATES INSTRUCTIONS FLYER.

THERE ARE SEVERAL DIFFERENT DESIGNS OF PUSH-ON JOINTS FOR DUCTILE-IRON PIPE AND FITTINGS. BE SURE THAT THE CORRECT GASKET IS USED.

IT IS ESPECIALLY IMPORTANT THAT THE GASKET IS INSTALLED IN A CLEAN BELL.

THE GASKET GROOVE IN THE TYTON OR FASTITE BELL SHOULD NOT BE LUBRICATED PRIOR TO GASKET INSERTION.

JOINT ASSEMBLY PROCEDURE

STEP 1. BELL CLEANING: Thoroughly clean out the bell. Remove all foreign matter: dirt, sand, mud, ice or excess paint.
STEP 2. PLAIN END PREPARATION: Clean off the plain end, removing any dirt, foreign matter or excess paint. Make sure that the plain end is beveled. File smooth any sharp edges which might damage the gasket.
STEP 3. GASKET INSERTION: Insert the gasket in its recess in the bell, with the large end of the gasket just prior to joint assembly. Make certain the entire inner surface of the gasket is coated. Also apply a thin coating of lubricant to the beveled portion of the plain end.
STEP 4. JOINING: Guide the plain end into the bell and compress the gasket by pushing the plain end all the way into the bell socket. Keep the bell and plain end in reasonably straight alignment during assembly. Any deflection should be taken after the joint is assembled.

MECHANICAL JOINT

THE PROCEDURES DESCRIBED BELOW SHOULD BE FOLLOWED TO ASSURE PROPER JOINT ASSEMBLY.

THERE ARE SEVERAL DIFFERENT SIZES OF BOLTS. CHECK TO SEE YOU HAVE PROPER SIZE AND NUMBER.

STEP 1. BELL AND SPIGOT CLEANING AND LUBRICATION: Thoroughly clean bell gasket area and spigot of pipe of all foreign material. Lubrication and additional cleaning should be provided by brushing both the gasket and plain end with soapy water or pipe lubricant just prior to slipping gasket into the plain end.
STEP 2. GLAND AND GASKET: Place gland with lip extension toward the plain end, and the gasket with the narrow edge toward the plain end of the pipe.
STEP 3. JOINING: Insert the pipe into the bell and press the gasket firmly and evenly into the gasket recess. Keep the joint straight during assembly. Make deflection after joint assembly but before tightening bolts. (Lubrication as in Step #1 will help facilitate gasket seating.)
STEP 4. BOLTS: Push the gland toward the bell and center around the pipe with the gland lip against the gasket. Insert bolts and hand-tighten the nuts.
STEP 5. TIGHTENING: Tighten bolts to normal range of bolt torque as indicated in table. Maintain approximately the same distance between gland and the face of the bell flange. This is done by partially tightening the bottom bolts first then the top bolts next bolts on either side, finally the remaining bolts. This is repeated as many times as required.
