Parker 4100SGBL-2000 2"x10' Dual Coupler Male Aggressive Chemical Transfer Hose

This is a new Parker Series 4100 "Aggressive Chemical Transfer" hose assembly, part number 4100SGBL-2000, configured as a 2-inch ID x 10-foot length with a distinctive blue/yellow spiral PVC cover and stainless steel male NPT end fittings on both ends (one male NPT x one female NPT based on photo — one end threaded male, one end hex-style female). The 4100 series is constructed with a UHMWPE (ultra-high molecular weight polyethylene) tube that provides broad chemical resistance to acids, alkalis, solvents, and other aggressive media, reinforced with a rigid PVC spiral helix for full vacuum and pressure service. Per markings visible in the photos, the hose is rated for a maximum working pressure of 230 PSI and a full vacuum rating of 29 in/Hg, with a safety factor of 4:1 (FS 4:1 MAX WP 230 PSI), and is made in the USA. Typical applications include chemical plant transfer, tank truck loading/unloading, drumming operations, and suction/discharge of acids, caustics, and solvents; the stainless steel fittings are compatible with aggressive chemical environments where carbon steel would be unsuitable.
