Technical Information Sheet
Smith Little Torch
Hose Replacement Instructions

The Little Torch hose is manufactured of a special material designed to be compatible with oxygen and the various fuel gases at recommended pressures. Test results have shown this new color coded hose will give longer service life through increased abrasion resistance, burst pressure, and flexibility.

Replacement hose is available in 6' or 12' lengths. Do not use hose lengths in excess of 12' or other than genuine Smith replacement parts.

Little Torch Replacement Hoses
Hoses are supplied with connections.

Identify the specific model number by referring to the model number stamped on the black handle of the torch body, then refer to the specific instructions for that model.
Model 11-1101 Torch Body or
Models 11-1101C, 11-1102C, 11-1103C, 11-1104C Torch Bodies

The following instructions apply only to this model torch body. Check instructions for your specific torch body number as stamped on the black handle tube.

To Remove Old Hose
Immerse torch, (11-1101 torch body) hoses, and connections in hot water (nearly boiling) to soften old hose. After a few minutes, hose will be sufficiently soft to be easily pulled from fitting nipple on torch head. Care should be exercised to prevent burns from heated parts.
 

To Attach New Hose
1.  Check that regulator right hand thread nut is on green hose and left hand thread (grooved) nut is on red hose. Place new ferrule on each hose with chamfered end facing toward torch body. Slide ferrules down each hose one to two inches.
2.  Slide the green hose over the green barbed nipple at the back of the torch until hose is 3/16" past the barb on the nipple.
3.  Push metal ferrule onto barbed nipple. Slip hose into ferrule tool below ferrule and slide tool against end of ferrule.
4.  Hold torch so that ferrule tool is resting on top of vise, jaws opened to approximate width of hose. With a plastic hammer, wood block or equivalent, tap lightly on end of tubing or socket until the metal ferrule just covers the barbs of the nipple. Remove ferrule tool.
5.  Repeat instructions for red hose.
6.  TEST FOR LEAKS.

Close torch valves and pressurize torch (both hoses) to approximately 10 to 12 psig. Immerse torch in water and check connections and torch for leaks (bubbles). If a leak is not observed the torch is now ready to use. If leak is observed, DO NOT USE TORCH. RETURN TORCH TO SMITH EQUIPMENT WITH EXPLANATION OF THE PROBLEM.
