For extreme pressure service when a metallic pigtail is required. Style SF4500 all-stainless steel, all-welded hoses are a zero permeation product, ideal for specialty/high purity gases. the 4500 PSIG rating is the highest in the industry for metal hose pigtails. Optional stainless steel armor casing provides additional life, safety, and protection. Each assembly is tested to 1-1/2 times MAWP. Branded with part number, manufacturer, size, MAWP, and month/year.
These pigtails are ideal for small molecule gases such as helium and hydrogen that may effuse through the walls of other types of pigtails. The inherent properties of 316 stainless steel also are ideal for specialty gas applications. Consider SF4500 for permanent on-site installations in connection to distribution and switch-over manifolds*. Each pigtail assembly is pressure tested at 150% of the rated working pressure using nitrogen under water. Optional testing can include mass spectrometer helium leak tests using customer specifications.
End fitting options are male NPT, female NPT, compression tube, or face seal (male or female). Assemblies can be cleaned for oxygen service to meet CGA specification G-4.1. Cleaned pigtails will be capped and packaged in clear bags with “oxygen clean” certification cards. CGA nuts, nipples, check-valve nipples, hand-tight nuts, elbows, or distance pieces may be specified to be installed on the assemblies. * Note: Due to the damaging effects of high velocity gases on the corrugated innercore, metallic core hose in not recommended for cylinder filling applications.
