2 Inch x 1.5m SS304 Braided Hose with Galvanized Union Ends

This configuration is a 2 inch (DN50) bore SS304 braided flexible hose, 1.5 meters long, fitted with a galvanized union connection on both ends, built to a 25 bar service rating. JOHOB's standard catalog braided hose runs single-braid construction rated to 100 PSI (7 bar) working pressure and 300 PSI (21 bar) burst, which is below the 25 bar (roughly 362 PSI) this spec calls for. To meet 25 bar, the assembly is built with double-braid SS304 construction instead of the standard single braid, and the working pressure is confirmed against your spec before fabrication starts, not assumed from a catalog table. Bore size, overall length, union thread or flange standard (BSP, NPT, or metric), and union body material are locked in at the quote stage so the fabricated assembly matches the spec sheet line item exactly, including the tolerance on the 1.5m overall length. Because this falls outside our standard ex-stock range, it is quoted and built to order rather than pulled from inventory.

Pairing an SS304 hose body with a galvanized (zinc-coated carbon steel) union creates a dissimilar-metal joint. In a humid or wet service environment, that joint can set up galvanic corrosion at the union face, with the less noble metal (the galvanized coating) wearing away faster than it would in a same-metal joint. This is a real risk on this exact spec, not a theoretical one, because the query explicitly calls for galvanized unions on both ends of a stainless hose. JOHOB's custom fabrication line offers a dielectric union insert as an option on this configuration: it electrically isolates the stainless hose body from the galvanized union so the two metals are not in direct contact, which is the standard way to prevent galvanic wear at a dissimilar-metal joint. If the application calls for the union to stay galvanized for compatibility with existing galvanized pipework downstream, flag that at RFQ stage so the dielectric break can be specified alongside it, rather than discovered after installation.

JOHOB sources this hose through an ISO 9001 certified partner factory, with the base material TUV SUD tested as part of our standard certification set on supplied equipment. For a 25 bar spec, the working pressure is verified against the order before the assembly ships, since a 2 inch double-braid build behaves differently under pressure than a 1/2 inch or 1 inch line of the same construction. Union ends are torqued and leak-checked after assembly, and the final bore size, overall length, and end-fitting type are checked against the original RFQ line item before the unit is packed for nationwide delivery. If the galvanic corrosion point raised above applies to your installation, the dielectric union option is fitted and verified at this same stage, not left for the installer to catch on site.

This configuration is quote-based, in line with our standard terms: we do not publish fixed pricing for custom hose assemblies because bore size, length, union metallurgy, and pressure rating all move the fabrication cost. We respond to RFQs within 1 business day. Because a 25 bar, galvanized-union, 2 inch x 1.5m build sits outside our ex-stock range (which covers 21 to 35 day lead times), this spec is handled as made-to-order, with a 45 to 90 day lead time from order confirmation to delivery. 12% VAT applies if you are a VAT-registered buyer; PEZA and SBMA locators and exporters qualify for zero-rated VAT on the same line item. Delivery covers NCR, the rest of Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark zone addresses nationwide, so the lead time above is the same regardless of which region the installation site is in.

A 2 inch flexible hose rated to 25 bar with galvanized union ends is typically a connector segment, not a standalone line: it absorbs vibration and minor misalignment at a point where two pieces of rigid pipework meet, commonly near a pump discharge or suction line in a booster, transfer, or submersible pump system, or at a panel-fed section of piping where a VFD duplex panel is cycling the pump on and off. The galvanized union end usually means the rest of the run on at least one side is galvanized steel pipe, which is consistent with retrofit or extension work on an existing galvanized system rather than a brand-new all-stainless installation. If this hose is going into a pump system, it is worth confirming the pump and panel specs at the same RFQ stage so the hose, union metallurgy, and pressure rating are sized to the actual duty point instead of to a generic 25 bar figure.
