    BenchRebel Silicone Seal & Gasket Restoration Kit – Vintage Ritter Model C

    Bring your century-old compressor back to life with a leak-free, precision-fit silicone seal kit.

    Finding replacement seals and gaskets for a vintage Ritter Model C air compressor shouldn't fall back to cutting cork gaskets that degrade, do not like repeated refills of the oil reservoir, and ultimately degrade contaminate the oil. The BenchRebel Restoration Kit is custom-engineered from 40A Shore hardness pure silicone to match the original Ritter Model C geometry — thick enough to compensate for decades of pitting, warping, and surface corrosion, and flexible enough to create a reliable, leak-free seal every time without imprinting.

    Compatible With: Vintage Ritter Model C Air Compressor (circa 1920s)

    Kit Includes

    • 1 Oil Reservoir Seal (small)
    • 1 Oil Reservoir Seal (large)
    • 1 Crankcase Gasket

    Features & Benefits

    • Custom-engineered fit – Precision dimensions matched to the Ritter Model C oil reservoir and crankcase, so you spend less time trimming and more time running.
    • 40A Shore hardness silicone – Soft enough to conform to irregular, aged surfaces; firm enough to hold a reliable seal under pressure.
    • Compensates for surface wear – Extra thickness accounts for pitting, warping, and corrosion that accumulates on cast iron surfaces over a century of use.
    • Reusable and durable – Unlike cork or paper gaskets, pure silicone seals can be removed, cleaned, and reinstalled during routine maintenance without tearing or degrading.
    • Oil and chemical resistant – Silicone construction resists petroleum-based compressor oils and common solvents used during restoration.
    • High-temperature stable – Maintains a reliable seal across a wide temperature range, from cold shop starts to sustained compressor operation.
    • No adhesive required – Compression fit design holds the seal in place without gasket cement or sealant, making future maintenance straightforward.

    Why Silicone Over Cork or Paper Gaskets?

    • Longer service life – Silicone outlasts cork and paper gaskets that dry out, crack, and crumble over time.
    • Reusable – Remove and reinstall during oil changes without sourcing a replacement every time.
    • Better conformability – Silicone flexes to fill surface imperfections that rigid gasket materials can't bridge.
