Step 2. Step 4. Step 5. Cut hose squarely to length. Use hose cut-off machine or fine tooth hacksaw. Do not remove the cover if using a hacksaw; wrap hose with several layers of tape before cutting. Place socket in vise. Do not overtighten vise on thin walled sockets of lightweight fittings. Screw hose counter-clockwise into socket until it bottoms. Back off 1/4 turn. Lubricate inside of hose and nipple threads liberally. Use lubricating oil, petrolatum or light grease. Screw nipple into socket and hose using wrench on assembly tool hex. Nut must swivel freely when assembly tool is removed. Maximum allowable gap between nut and socket is 1/16". On -32 screw in until turning becomes difficult, back out nipple, relubricate and reassemble. Step 3. Tighten nipple and nut on ssembly mandrel. The use of Aeroquip S1051 hand assembly tools are recommended to avoid damage to the sealing surface and to properly support the inner tube. Elbow Hose Assemblies - 303 and 302A Step 1. Step 3. Step 5. Step 6. Cut hose squarely to length. Use hose cut off machine or fine tooth hacksaw. If using a hacksaw, wrap hose with tape before cutting. Do not remove cover. Flange elbow fittings. Drop flange over threaded end of nipple. Nipple shoulder must fit into counter bore of flange. Screw nipple into socket and hose using wrench on elbow hex. Tighten until hex is snug against socket. On -32 and larger sizes, screw in until turning becomes difficult, back out nipple, relubricate and reassemble. Adjustments may be necessary to obtain the desired position angle between two elbows. In order to minimize backing off elbows to position, the following procedure should supplement Step 5. Step 2. Place socket in vises. Do not overtighten vise on thin walled sockets of lightweight fittings. Screw hose counter-clockwise into socket until it bottoms. Back off 1/4 turn. Step 4. Lubricate inside of hose and nipple threads liberally. Use lubricating oil, petrolatum or light grease. A.Tighten both elbows to maximum allowable gap (reference Step 6C), then start to position for relative angle between the elbows. B.Finish assembly by adjusting both elbows. Backing-off to position should be avoided and in no case should exceed 1/4 turn. C.Maximum allowable gap between nipple hex and socket is 1/16" using 303 and 302A hose.
