  1. General Information<\/li>\n<\/ol>\n

    – Product: No-Hub Coupling<\/a> for DWV System<\/p>\n

    – Applicable Pipe: Hubless cast iron drainage pipe<\/p>\n

    – Size Range: DN50 \/ DN75 \/ DN100 \/ DN150 \/ DN200<\/p>\n

    – Standards: ASTM C1277, ASTM A888<\/p>\n

    \"No-Hub<\/p>\n

    Recommended Tightening Torque<\/p>\n

    Bolt Torque<\/p>\n

    DN50 5–6 N·m<\/p>\n

    DN75 6–8 N·m<\/p>\n

    DN100 8–10 N·m<\/p>\n

    DN150 10–12 N·m<\/p>\n

    DN200 12–14 N·m<\/p>\n

    – Tighten crosswise, step by step<\/p>\n

    – Do not over-tighten to avoid gasket damage<\/p>\n

    Alignment Tolerance<\/p>\n

    – Axial gap \uff1a≤ 3 mm<\/p>\n

    – Radial offset \uff1a≤ 0.3% of pipe diameter<\/p>\n

    – Angular misalignment \uff1a≤ 1°<\/p>\n

    – Deflection compensation \uff1a≤ 3°<\/p>\n

      \n
    1. Installation Steps<\/li>\n
    2. Clean pipe ends, remove burrs & rust<\/li>\n
    3. Slide rubber sleeve onto one pipe<\/li>\n
    4. Butt pipes and keep concentric<\/li>\n
    5. Position gasket at center of joint<\/li>\n
    6. Install stainless steel clamp<\/li>\n
    7. Tighten bolts crosswise to rated torque<\/li>\n<\/ol>\n

      Final Inspection<\/p>\n

      – Gasket evenly compressed, no extrusion<\/p>\n

      – No visible gap between clamp and gasket<\/p>\n

      – Pipes aligned, no obvious deflection<\/p>\n

      – No leakage in water \/ pressure test<\/p>\n

      – No abnormal noise when running<\/p>\n
