Easily Vacuum Cap Kit — 202-Pc Rubber Vacuum Plugs & Hose End Caps, 8 Sizes (Assorted) — Heat‑Resistant, Tear‑Resistant

Easily Vacuum Caps Rubber Plug Kit is a 202-piece assortment of eight-size rubber vacuum plugs and hose end caps designed to seal carburetors, manifolds, hoses, and ports during maintenance and repair.

This compact kit gathers a complete range of flexible, high-temperature rubber plugs in a clear plastic storage case so you can block vacuum lines, protect sensors, and cap open fittings quickly. Each cap is molded to provide a snug, airtight fit across common automotive and HVAC inner diameters, helping prevent vacuum leaks and keeping debris out while you work.

Which sizes are included and how many of each will I get?

The kit contains eight distinct inner-diameter sizes totaling 202 caps, curated to cover most small engine, automotive and HVAC vacuum jobs. Sizes are listed with approximate lengths so you can choose the correct plug for shallow or deeper ports.

• 5/16" ID (1-1/4" length): 18 pieces
• 3/8" ID (1" length): 12 pieces
• 7/32" ID (47/64" length): 24 pieces
• 5/32" ID (39/64" length): 35 pieces
• 1/4" ID (1-1/4" length): 25 pieces
• 5/16" ID (7/8" length): 18 pieces
• 3/16" ID (11/16" length): 35 pieces
• 1/8" ID (9/16" length): 35 pieces

How durable are these rubber plugs for workshop and outdoor use?

These caps are made from a flexible, tear-resistant rubber compound engineered to resist heat, UV, and corrosion so they hold up under typical automotive and HVAC conditions. They maintain elasticity across temperature swings and provide reliable electrical insulation where needed.

• High temperature and UV resistance reduces cracking and hardening
• Corrosion resistance protects metal fittings and sensors
• Thick, solid walls resist tearing and repeated use

What practical jobs do the plugs handle during repairs or maintenance?

Use the plugs to temporarily seal vacuum lines, block off manifold or carburetor ports, protect sensors and fittings from dirt, and cover cut tubing ends to prevent injury. They’re useful for leak testing and for keeping systems sealed while individual components are serviced or replaced.

• Temporary vacuum line sealing for diagnostics and leak checks
• Covering emissions and maintenance ports during repairs
• Protecting sensitive sensors and fittings from debris
• Covering sharp tubing ends to prevent cuts and damage

How is the kit organized for easy use in a busy garage?

The plugs come sorted inside a clear, hinged plastic case so you can see quantities and sizes at a glance. The compact case is portable and keeps sizes separated so you spend minutes finding the right cap instead of searching through loose parts.

• Transparent storage box for quick visual identification
• Individual compartments prevent mixing of sizes
• Compact footprint fits on a workbench or mobile cart

Who is this for: The Easily Vacuum Caps Rubber Plug Kit is aimed at mechanics, DIY enthusiasts, HVAC technicians, and automotive hobbyists who need a ready selection of reliable rubber caps for testing, temporary sealing, and protection during maintenance. If you perform routine repairs, diagnostic checks, or sensor service on engines and HVAC systems, this kit saves time and reduces the risk of contamination or vacuum leaks while you work.
