How to Choose the Right Connector
Choosing the correct vacuum connector is straightforward if you know the inside diameter (I.D.) of your hose:
- Measure the hose I.D. with a caliper or compare against a sample connector from the kit.
- Select a connector whose listed I.D. matches or sits snugly inside the hose to ensure a tight seal.
- For branching vacuum lines, use the appropriate tee size; use reducers when joining different hose diameters.
Installation Tips & Maintenance
- Before fitting, clean hose ends of dirt and old sealant; a clean surface ensures a reliable seal.
- Heat in engine bays can soften low-grade plastics — Nylon 66’s high heat resistance reduces deformation and failure risk.
- For long-term secure connections on pressurized lines, consider adding a small hose clamp in tight or safety-critical areas.
- Store unused pieces in the provided bags and away from direct sunlight to preserve material properties.
Frequently Asked Questions
- Are these connectors suitable for fuel lines?
- These connectors are formulated for vacuum and small air/fluid tubing applications. They are not recommended for modern liquid fuel systems without checking chemical compatibility. For fuel applications, use connectors specifically rated for fuel.
- Will the connectors withstand engine temperatures?
- Yes — the kit uses Nylon 66 with heat resistance up to 240 °C (460 °F), making it suitable for many under-hood vacuum applications.
- How many pieces of each size are included?
- The kit is packaged as a 115-piece assortment distributed across the twelve sizes; pieces are organized in separate transparent bags for quick access.
