Style SF82 Monel, all-welded hoses are a zero permeation product. Ideal for corrosive gases or oxygen applications where a Monel hose is called for. 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, MAWP, and month/year.
SF82 Monel pigtails are constructed with a helical close-corrugation Monel core, insuring high-purity, zero effusion, and excellent flexibility. Two stainless steel braids provide extremely high working pressure—4250 PSI MAWP with a 4:1 safety factor. Welded end connections are constructed using Monel. Optional stainless steel armor is flexible and streamline, enhancing kink resistance, braid protection, and anti-whip protection.
Each SF82 Monel assembly is permanently marked with manufacturer, pressure rating, and date of manufacture-- meeting CGA requirements, providing easy identification, and promoting safety. These pigtails are ideal for small molecule gases such as helium and hydrogen that may effuse through the walls of other types of pigtails. Consider SF82 Monel 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 Monel male NPT or female NPT. Monel CGA fittings can be special ordered. 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. * Note: Due to the damaging effects of high velocity gases on the corrugated innercore, metallic core hose in not recommended for cylinder filling applications.
