The Multiquip 0126004005 Check Valve is a genuine OEM component designed for DIS185SSI4F and DIS100SSK4F air compressors. Sourced directly from Multiquip, this check valve meets the exact specifications of the original part, ensuring correct function within the compressed air system. It is a direct-fit replacement confirmed for DIS185SSI4F and DIS100SSK4F models, with no adaptation required to install it in the designated valve position.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original valve seat tolerances and pressure ratings, so flow direction control performs exactly as designed for these compressors.
- Direct-Fit Replacement — Matches the original port dimensions and connection interface of the DIS185SSI4F and DIS100SSK4F, dropping straight into the existing valve housing.
- Confirmed Fitment — Verified for DIS185SSI4F and DIS100SSK4F air compressor models using Multiquip OEM parts data.
- Sustained System Pressure — A properly functioning check valve prevents backflow and pressure bleed-down between cycles; a worn or failed valve causes pressure loss, longer pump cycles, and excessive compressor wear.
- Pressure Integrity Assurance — In compressed air systems, a failed check valve can allow pressurized air to reverse through the pump head, creating a safety risk; replacing with a genuine OEM valve restores correct one-way flow control.
A check valve is a one-way flow control component that allows compressed air to pass in a single direction while preventing backflow into the pump or upstream circuit. In an air compressor, it holds tank pressure between pump cycles and protects the pump head from reverse pressure loading. When a check valve fails — through wear, debris fouling, or a damaged seat — the compressor loses the ability to maintain tank pressure efficiently, leading to short-cycling, increased motor load, and potential damage to downstream components.
