    Item #N/A

    Taco 1600 Series Pump Repair Kit — 1600-868CRP

    The Taco 1600 pump repair kit is a direct-fit replacement for Taco 1600 Series in-line circulator pumps, referenced as Taco 1600-868CRP. Supplied complete with the mechanical seal, the machined bronze shaft sleeve 1600-205RP, the gasket set and the left-hand thread mounting bolt — every wear part the rebuild takes, in one box. Built to OEM-equivalent standards or higher. Unlike the original, our shaft sleeve is machined from solid bronze rather than die-formed from sheet — a truer, heavier wear surface that gives the seal a longer service life.

    What’s included

    • Mechanical seal — in your choice of material

    • Shaft sleeve — machined solid bronze, replaces Taco 1600-205RP

    • Gasket set for reassembly

    • Left-hand thread mounting bolt (matches factory rotation/retention)

    Available Versions

    Same kit, same fit — the difference is the seal material inside. Choose your build from the dropdown above.

    Most hydronic heating and chilled-water systems take the Carbon/Ceramic/EPDM build — the same material pairing Taco ships as standard. Step up if your system carries chemicals, or grit that wears seals out early.

    Kit Taco Kit No. Max °F Choose This If
    Standard – Carbon/Ceramic/Nitrile Seal House build 200°F Clean water at neutral pH — ordinary HVAC, booster and general water service.
    Upgrade – Carbon/Ceramic/EPDM 1600-868CRP 300°F Hot water and glycol systems. This is Taco’s standard kit — EPDM stays flexible where Nitrile hardens.
    Upgrade – Carbon/Silicon Carbide/EPDM Seal House build 300°F Same hot water and glycol duty with a harder seat — for seals wearing out early.
    Heavy Duty – Silicon Carbide/EPDM Seal House build 300°F Hot water or glycol carrying grit or solids. Both faces silicon carbide.
    Upgrade – Carbon/Ceramic/Viton Seal House build 450°F Higher temperatures, bleach, aggressive chemicals.
    Top gradeHeavy Duty – Silicon Carbide/Viton 1600-868SRP 450°F Chemicals plus abrasives. Taco’s high-temperature kit, and the hardest faces we offer.

    Seal material builds and Taco kit numbers

    The build you select cross-references to a different Taco kit number. All of them fit the same 1-1/8 in. shaft on CE, FE and VI pumps.

    • Cross-references to Taco 951-3161BRP — carbon and ceramic faces with Nitrile (Buna) elastomers. The standard build.

    • Cross-references to Taco 951-3161BRP-EP — the same faces with EPDM elastomers, for hot water and glycol.

    • Cross-references to Taco 951-3161BRP-VT — the same faces with Viton elastomers, for higher temperatures and chemicals.

    • Our silicon carbide builds are Seal House specifications. Taco does not offer a silicon carbide seat in this kit family.

    This kit takes a 1.00 x 1.12 x 2.06 in. shaft sleeve. If your sleeve measures 1.93 in. long, you need the Taco 953-1549-3BRP kit instead — both carry the same 356 seal, and sleeve length is what separates them.

    Why this kit

    • Better fitment: Our seal uses a crimped-head design with a custom-matched spring-to-sleeve combo for consistent working length and tight sealing—often a more accurate fit than generic aftermarket kits.

    • Hydronic-ready: Materials selected for high-temp/high-pressure duty.

    • All-in-one convenience: Everything needed for a clean, efficient rebuild.
