F2159 Application Problems

See limitations illustrated in F1807 regarding calibrated

tool, square-cut tube, fully inserted ttings and properly

positioned ring.

Purple primer can be seen to have negatively affected

the tting. Be sure excessive oil on any connection

system component does not contact the PPSU material.

Fittings that have become subject to solvents (PVC

primers/glues included) are negatively chemically

affected and MUST be removed from service.

Do not subject PPSU/PSU material to an open ame or

solder within 18" of plastic product.

Sioux Chief PPSU has been made white in color so that

any harmful chemical exposure or UV exposure can be

witnessed and suspect ttings can be removed from use.

Handling and Use !

Petroleum based products, solvents, PVC glues and

primers, gels, lubricants, pipe dopes, ethylene glycol,

thread oils and paste or other volatile compounds should

not come in contact with PPSU ttings. Store ttings

away from harmful chemicals and direct sunlight (UV

exposure). The maximum short-term working temperature

(30 days) of ttings: 210 ºF (99 ºC) @ 150 PSI. Constant

Working Temperature: 140 ºF (60 ºC) @ 55 PSI. PPSU

should not be used in any installation within mechanical

systems that may have oil or solvent residue. Do not

impact PPSU/PSU polymer ttings. Do not subject ttings

to torque limits exceeding 100 lbs. of force. Fittings

should be kept free of mechanical stress. Each joint

should be properly supported.
