These 5mm silicone hose end caps from uxcell are ideal for automotive technicians, DIY mechanics, and hobbyists looking to secure, protect, or seal various fluid and vacuum lines. They provide a reliable, flexible seal for stainless steel hoses, alloy hard pipes, and silicone vacuum lines, though users should ensure the diameter matches exactly to prevent slippage on high-pressure applications.

These are intended for vacuum lines and hardware protection. They are not recommended for pressurized fuel systems.
Yes, they are made of silicone, which is designed to withstand typical engine bay operating temperatures.
No, prolonged exposure to oil may cause the silicone to swell or degrade. They should only be used for vacuum or air applications.
No, the set includes 100 pieces of silicone end caps only.
Yes, you can easily trim the caps with a sharp hobby knife if you need a lower profile.
Ensure the pipe surface is clean and degreased; consider adding a small zip tie to secure the cap.
Apply a tiny amount of silicone-safe lubricant or water to the inside of the cap to help it slide over the pipe.
Verify your pipe diameter is actually 5mm; if the pipe is smaller, the cap will not provide a vacuum-tight seal.
Installation is straightforward: simply push the cap over the end of the pipe or screw until it reaches the base. For a tighter fit, you may use a small zip tie or hose clamp if vibration is expected. These caps are compatible with any rigid or semi-rigid tubing measuring 5mm in outside diameter. To care for the caps, avoid contact with sharp metal burrs that could puncture the silicone. If the caps become coated in grime, they can be cleaned with mild soap and water; avoid using harsh degreasers that may cause the silicone to soften over extended periods.
