asc-es.comSCI® Press - Copper FittingsApplications*Fluids containing hydrocarbon-based oils are not compatible with the EPDM seal.All copper tubing must comply with the ASTM B88 standard. Fittings are approved for installations above and below ground as permitted by local building codes.Copper Fitting Alloy C1220 has been evaluated by IAPMO R&T Lab to NSF/ANSI 61 for use in drinking water supplies of pH 6.5 and above. Drinking water supplies that are less than pH 6.5may require corrosion control to limit leaching of copper into the drinking water.PS-10.22 page 2 PS-SUB-SCI Press-Cooper-v01 20221020SCI Press Copper Fittings are intended for use with ASTM B88 seamless copperwater tube (Types K, L, & M) in residential and commercial plumbing andmechanical systems. Common applications are listed below:
