    This rubber bush is used when servicing the water-level indicator assembly of garment steam boilers and pressurized steam generators. It is particularly useful when replacing a worn, hardened, cracked, or leaking sealing bush during sight-glass maintenance.<\/p>\n

    It can be used by:<\/p>\n

      \n
    • Garment factories maintaining multiple steam boilers<\/li>\n
    • Tailor and pressing shops using boiler steam irons<\/li>\n
    • Boutiques with steam pressing equipment<\/li>\n
    • Home users maintaining compatible steam-generating equipment<\/li>\n
    • Technicians replacing boiler sight-glass components<\/li>\n<\/ul>\n

      Reliable sealing around the glass:<\/strong> The bush compresses around the sight glass to help contain steam and water inside the gauge assembly.<\/p>\n

      Heat-resistant construction:<\/strong> The elastomer is designed for the elevated temperatures encountered around steam boiler water-level gauge assemblies.<\/p>\n

      Tapered profile:<\/strong> The conical shape helps the bush seat firmly in the gauge housing instead of relying only on a flat contact surface.<\/p>\n

      Glass protection:<\/strong> The flexible sealing material provides cushioning between the glass tube and surrounding gauge components, helping accommodate vibration and thermal movement.<\/p>\n

      Easy maintenance replacement:<\/strong> The bush can be replaced during routine sight-glass servicing instead of replacing the complete gauge assembly when only the seal is worn.<\/p>\n

      First<\/strong>, switch off the boiler, isolate it from steam and water pressure, and allow the assembly to cool completely before starting maintenance.<\/p>\n

      Next<\/strong>, remove the existing sight-glass assembly components carefully and inspect the glass tube, gauge housing, washers, nuts, and sealing surfaces for damage, scale, or debris.<\/p>\n

      Then<\/strong>, position the new rubber bush correctly around the compatible sight glass and reassemble the gauge components according to the original assembly arrangement. Make sure the glass is properly centered before tightening.<\/p>\n

      Finally<\/strong>, tighten the assembly securely without excessive force, restore the boiler connections gradually, and check the sight-glass area for steam or water leakage during operation.<\/p>\n

      1. What is a boiler glass rubber bush used for?<\/h4>\n

      A boiler glass rubber bush seals the area around the water-level sight glass in a steam boiler gauge assembly. It helps prevent steam and water from escaping around the glass while allowing the glass to remain cushioned inside the fitting. It is commonly replaced during sight-glass servicing when the existing seal becomes worn, hardened, cracked, or starts leaking.<\/p>\n

      2. Can this rubber bush be used when replacing a boiler sight glass?<\/h4>\n

      Yes, it is intended for use as a replacement sealing component during compatible boiler sight-glass maintenance. The bush works with the gauge assembly to seal around the glass tube. Before ordering, compare the existing bush, glass tube, and gauge housing because sight-glass assemblies can use different dimensions and sealing profiles.<\/p>\n

      3. Does the rubber bush fit 3L, 5L and 6L steam boilers?<\/h4>\n

      This bush is suitable for compatible 3L, 5L and 6L garment steam boiler water-level gauge assemblies. Boiler capacity alone does not determine the correct bush size. The physical dimensions and seating arrangement of the existing sight-glass assembly should be checked before purchase to ensure the replacement seats correctly.<\/p>\n

      4. What causes a boiler sight-glass rubber seal to leak?<\/h4>\n

      A sight-glass seal can leak when the rubber becomes hardened, damaged, incorrectly positioned, or compressed unevenly. Dirt, scale, corrosion, or damaged sealing surfaces can also affect sealing. If leakage continues after replacing the bush, inspect the glass tube and gauge fittings rather than repeatedly tightening the assembly.<\/p>\n

      5. Should the rubber bush be replaced when changing the sight glass?<\/h4>\n

      Replacing the sealing bush during sight-glass replacement is good maintenance practice because the old seal may already have lost elasticity or developed compression damage. Technical guidance for sight-glass servicing also emphasizes inspecting and replacing sealing components when the glass is changed.<\/p>\n

      6. Can I use this bush on any boiler water-level glass?<\/h4>\n

      No. It should be used only where the bush’s physical profile and dimensions match the existing gauge assembly. Water-level gauge systems use different glass and sealing arrangements, so matching the replacement to the existing component is important. Check the old bush and gauge housing before ordering, especially when replacing a non-standard sight-glass assembly.<\/p>\n

      7. How tight should the sight-glass assembly be after replacing the bush?<\/h4>\n

      The assembly should be tightened securely enough to compress the seal and prevent leakage, but it should not be overtightened. Excessive force can damage the glass or sealing components. Sight-glass maintenance guidance specifically warns against overtightening because glass can break under excessive tightening force.<\/p>\n

      8. Is this rubber bush supplied as a complete water-level gauge?<\/h4>\n

      No. This listing is for 1 rubber bush only<\/strong>. The sight glass, nuts, washers, valves, gauge body, and other boiler components are not included unless specifically stated in the product listing.<\/p>","protected":false},"excerpt":{"rendered":"
