SS304 Steam Hose, DN25, Free Nut Ends Both Sides, 1.5m Length

This configuration is SS304 braided flexible hose built for steam distribution lines, specified as DN25 (1 inch nominal bore) with free nut (swivel/union nut) end connectors on both sides. DN25 is available in JOHOB's standard pressure classes, PN10 and PN16, with female BSP, male NPT, or ANSI 150 RF flange termination options against an SS304 weld-nipple free end. The 1.5m length referenced here is one of the standard configurations JOHOB quotes for this bore size; custom lengths from short jumpers up to multi-meter runs are available through a written quote, since JOHOB does not publish fixed price lists. Free nut ends on both sides mean the hose can be installed and re-aligned without rotating the braided body itself, which matters on steam retrofits where flange or union bolt patterns are not perfectly matched to the hose run. Lead time on this configuration follows JOHOB's standard bands: 21 to 35 days for ex-stock configurations, or 45 to 90 days when the length, end-fitting combination, or pressure class requires a made-to-order build. Standard 12% VAT applies to VAT-registered buyers; PEZA and SBMA locators and exporters qualify for zero-VAT treatment. JOHOB responds to RFQs for this and other DN sizes within 1 business day, and delivers nationwide across NCR, Luzon, Visayas, Mindanao, and PEZA/SBMA/Clark zones.

A free nut, also called a swivel nut or union nut, is a threaded or flanged fitting that rotates independently of the hose body it is crimped or banded onto. When a hose has free nut ends on both sides, the installer tightens the connection by turning the nut, not the hose itself, so the braided body and its corrugated inner tube are not subjected to torsional stress during final tightening. On a DN25 steam line this is a practical installation detail: steam branch connections are frequently retrofit into existing headers where bolt patterns, flange orientation, or pipe stub alignment were not planned around a specific hose length. Free nut ends let the fitter rotate the connection into alignment after the hose is already routed, instead of pre-twisting the hose to match a fixed bolt pattern. This reduces the risk of over-torquing the wire braid or the weld-nipple joint during commissioning, which is one of the more common causes of early hose failure on steam lines that see thermal cycling. It also simplifies future maintenance, since a hose with free nut ends on both sides can usually be swapped out without disturbing the pipe stubs on either side of the connection. For plants standardizing on quick-swap steam hose assemblies across multiple point-of-use stations, specifying free nut ends on both ends (rather than one fixed, one free) keeps every spare interchangeable regardless of which side of the run it goes on.

DN25 (1 inch nominal bore) is a common branch-line size on steam distribution systems because it sits between small instrumentation tubing and full header pipe sizes, matching the flow requirement of individual point-of-use equipment rather than a whole plant's steam demand. In commercial and institutional facilities, DN25 branch connections typically feed equipment such as laundry presses and ironers, jacketed process kettles, autoclaves, and small heat exchangers, where the equipment's own steam inlet is already sized around a 1 inch connection. JOHOB's product line covers both the steam and boiler systems side of this (steam boilers, hot water, condensate handling) and the piping and fittings side (SS flexible hose, valves), which is why DN25 SS304 hose with free nut ends shows up as a standard configuration rather than a custom one-off. For buyers speccing a full steam distribution retrofit rather than a single hose, JOHOB's commercial and institutional verticals, including laundry equipment, cover the equipment side of this same DN25 connection point. As with all configurations, DN25 SS304 hose is quoted rather than price-listed, with lead time depending on whether the requested end-fitting and length combination is held ex-stock or needs to be built to order.

SS304 is the standard grade JOHOB quotes for DN25 steam hose and handles saturated and lightly superheated steam service in most Philippine plant environments. SS316 adds molybdenum to the alloy, which improves resistance to chloride-driven pitting and crevice corrosion, the failure mode most relevant in coastal or marine-adjacent installations, or in areas with frequent chemical washdown. For a plant located well inland with standard boiler feedwater treatment, SS304 is typically the appropriate and more cost-effective choice. For a plant at a coastal PEZA or SBMA site, or one where the hose run sits near frequent saltwater exposure or aggressive cleaning chemicals, SS316 is worth flagging on the RFQ even though it is not the default. Both grades are available through JOHOB in the same DN25, free-nut-ends, quote-based format described on this page; the grade decision does not change the lead time bands (21 to 35 days ex-stock, 45 to 90 days made-to-order) unless the SS316 configuration falls outside current stock. Buyers unsure which grade fits their environment should note the installation location (indoor/coastal/washdown-heavy) on the RFQ so JOHOB can confirm the right spec before quoting rather than after.

JOHOB does not publish fixed prices for DN25 SS304 steam hose or any other configuration; every order is quoted against the specific length, end-fitting, pressure class, and grade requested. Standard lead time is 21 to 35 days for configurations held ex-stock, and 45 to 90 days for made-to-order builds, such as non-standard lengths, uncommon end-fitting combinations, or SS316 grade where it is not already stocked. Standard 12% VAT applies to VAT-registered buyers in the Philippines; PEZA and SBMA locators and exporters qualify for zero-VAT treatment on qualifying purchases. JOHOB delivers nationwide, covering NCR, Luzon, Visayas, Mindanao, and PEZA/SBMA/Clark zones, and responds to RFQs within 1 business day. To request a quote for the DN25 SS304 free-nut steam hose (or a different bore size, length, or grade), submit the line size, pressure class, end-fitting type on each side, required length, and installation environment (indoor, coastal, or washdown-heavy) so JOHOB can confirm SS304 versus SS316 before returning a price.
