|1. Cutting the Fragola Performance Systems Series 3000 stainless braided hose is easy. Wrap the hose with duct tape at the length desired. Hose may be cut with a hack saw, if you have a 32-teeth-per-inch blade, otherwise a Beverly Shear, radiac, or chop saw will work fine. You want to keep the braids from fraying. After the cut, carefully remove the tape and trim from the frayed ends if necessary.
2. Using FPS aluminum vice jaws will help protect the hose from scratching during the next steps. If there is a concern about scratching, the hose end may be wrapped with tape for protection. Place the red socket in a vice, and insert the hose through the smooth end until the hose lines up with the bottom of the threads inside the socket.
|3. It is important to mark the outside of the hose at the end of the socket. This will show you if the hose has "pushed out" of the socket during assembly, and if so, will leak when used.|
|4. It is very important to lubricate the inside of the hose/socket assembly, and the outside of the cutter threads with any assembly lube, anti-seize compound, or 30 wt. Motor Oil. W/D-40 is not recommended!|
|5. Hold the hose and not the socket, start the hose on the nipple of the hose end, with a gentle motion. Continue pushing on the hose until the threads can be engaged. Some sizes may require the use of some force to engage the threads at this point.|
|6. It doesn't matter which portion (the socket or the nipple) is secure in the vice. Using a suitable wrench tighten the socket threads onto the cutter. An adjustable "Crescent" type wrench is not recommended, as it may slip and damage the outside of the hose end.
7. Tighten until the socket is within .060-.080" of bottoming out. Recheck your mark, and if it is within 1/16" of the socket your are OK. If not, disassemble the hose end, re-cut the hose and start all over again.
8. Clean the inside of the hose assembly with the clean solvent. Blow out residue with a compressed air. It is strongly recommended that you test the hose assembly for leakage before putting it into service. Be sure to lubricate the "B-nut" threads before installing on an adapter.
P.T.F.E. Hose Assembly
|You may cut the hose in the same method as our 3000 series hose.
With the hose cut to the desired length, you must first slide the "socket" onto the hose.
Next you must open up the braiding in order for the "olive" to slide over the PTFE liner. Our #900065 PTFE Braid Spreader works well in this application. The braid must be spread sufficiently so that small shoulder inside the "olive" rests against the cut end of the PTFE liner.
Push-Lite Hose Assembly
|Soften the end of the hose slightly in boiling water. Then oil the hose end nipple.
Clamp the hose end in a vice using our #900061 Aluminum Vice Jaws, and in one motion push the hose over the barb. The fit is tight on purpose, as it is the only method of hose retention.
Power Steering Hose Assembly
|You may cut the hose in the same manner as our Series 3000 Race Hose, but it is not necessary to tape the end prior to cutting.
Install the "socket" over the cut end of the hose. Some twisting may be required to get the "socket" to the desired position with the hose seated against the bottom of the socket.
Clamp the hose and socket in a vice using our #900061 Vice Jaws. Oil the tapered nipple with some form of motor oil/assembly lube, and screw the fitting all of the way in, until the socket seats on the fitting shoulder. Blow out with compressed air to remove any assembly residue.
|Fitting Size||Max. Torque in Foot Pounds||Many people over tighten the aluminum fitting on the adapter, which distorts the 37 degree seat, and may cause leakage. Both the threads and the seat surface should have a drop or two of oil to smooth the tightening process. The maximum torque specifications are listed here. (An alternate method of tightening is to bring the nut to "hand-tight" and then rotate it another turn with the proper wrench.)|
