(Chlorine Transfer Assembly) ChlorSafe™
ChlorSafe™ is Hose Master’s 276 alloy, corrugated chlorine-transfer assemblies, designed
specifcally to meet the demands of this application. With considerations made for both wet and dry
chlorine, these assemblies are the safest available. Hose Master’s ChlorSafe™ assemblies are
manufactured in compliance with the Chlorine Institute Pamphlet 6, Appendix A, latest edition.

Example: AF6720 = C276 annular corrugated metal hose with a single C276 braid
• The minimum bend radius is measured from the center-line of the hose
• Per Chlorine Institute specifcations, pressure ratings represent a 5:1 safety factor
• For pressures in excess of Chlorine Institute standards, please consult the factory

ChlorSafe™ Features:
• Hose Master’s unique hydroforming process reduces residual stress and produces the most
fexible chlorine-transfer hose available
• ChlorSafe’s™ all-metal construction makes it fre-resistant
• Proprietary welding techniques provide a smooth transition from hose to ftting with no gaps or
crevices to entrap contaminants
• All welds are argon-purged to eliminate oxidation
ChlorSafe™ Specifcations:
• All wetted surfaces and the braid are made from UNS N10276 (referred to as either C276 or 276
alloy) which has the highest chemical resistance rating for both dry and wet chlorine1
• Every assembly is helium mass spectrometer leak tested to at least 5.0 x 10-6 std cc/sec
• Each assembly is covered by a stainless steel interlocked metal hose for maximum durability
• All assemblies are strength-tested to twice maximum allowable working pressure
