Hose Assembly Coupling Installation Suggestionsfor Tigerflex Series TDH & TDHBK Gasoline Drop Hoses & Series TV & TVHD Gasoline Vapor Recovery Hoses using Tigerflex Banding Sleeves or Banding CoilsFor safety, Kuriyama of America, Inc. strongly suggests that any hoseassembly used to transfer gasoline or gasoline vapors be bonded toground before being put into service*.Tigerflex Hose Series TDH , TDHBK , TV and TVHD aremanufactured with a stranded copper wire in the rigid PVC helix. Thewire is to be physically extracted from the helix and bonded (connected)*Note: Visual inspections should be conductedon a regular basis to ensure the hose assembly’scontinued safety.Failure to properly couple a hose or ensure continuity can resultin property damage and serious or life-threatening injury!Kuriyama of America, Inc. shall not be liable if you do notfollow the procedures outlined below.to ground through the metal coupler/fitting, or by other means. A properlybonded/grounded hose assembly should measure less than 10 ohms*.The person assembling the couplings to the hose should know how tocheck the hose assembly for continuity by properly using a continuitymeter and/or an ohmmeter. Contact Kuriyama for training information.Read the Technical Bulletin on page 21 and 22 of this catalog.79Step 1 — Prior to coupling,check the grounding/bondingwire in the cut length of hosewith a continuity meter or ohmmeter(ohmmeter should readless than 10 ohms).2 Step 4 — Grasp the end ofthe hose’s helix and carefullybend it back and forth until thehelix snaps off. Be careful notto break the copper groundingwire.Step 2 — Using a sharp knife,cut the flex around the circumferenceof the hose approximately2”.3Step 3 — Using the knife, makea light cut around the entire circumferenceof the hose’s rigidhelix, including the urethane flex.Note: The copper groundingwire is located in the center ofthe helix . . . be careful not to cuttoo deeply into the helix, to avoiddamaging the grounding wire.TIP: Cut all the way through theurethane flex, but only score theunderside of the helix.45Step 5 — Gently pull thebroken end of the hose’s helixoff the copper wire. TIP: Pullclockwise, with the curve ofthe helix.6Step 6 — Twist the coppergrounding wire strands togetherand tuck the wire inside the hose.Step 7 — Screw approximately12” of banding sleeve onto thehose; use appropriate lubricantas needed. Or, thread thebanding coil between the helixesonto the hose. Slip thebanding clamps onto the hose.TIP: When using banding coils,tighten clamps in a clockwisedirection so the banding coiltightens down on the hose.8Step 8 — Insert the coupler’sbarbed shank into the hose,twisting counterclockwise as itenters. For ease of installation,an appropriate lubricant maybe used.Step 9 — Insert the coupler intothe hose until the hose seatsagainst the bottom of the coupler.Step 10 — Check continuity/ohmmeter reading again, betweenthe fittings on each end.11Step 11 — Install two hoseclamps over the hose end abovethe coupling. The clamp bucklesshould be located 180° apart.When using banding coils, besure to tighten clamps in aclockwise direction so the bandingcoils tighten down on thehose.Step 12 — Check continuity/ohmmeter reading again, betweenthe fittings on each end of thehose assembly. The resistanceshould measure less than 10 ohms.BECAUSE WE CONTINUALLY EXAMINE WAYS TO IMPROVE OUR PRODUCTS, WE RESERVE THE RIGHT TO ALTER SPECIFICATIONS WITHOUT PRIOR NOTICE.20KPPCA0308KPPCA0109
