Tallew 144-Piece Plastic Caps & Plugs Kit AN3–AN12, Red — Temporary Seals for Fuel, Brake & Hydraulic Lines

Tallew 144-piece plastic caps and plugs kit provides a full range of AN3–AN12 protective seals to block dust, stop leaks and keep fluid lines clean during service.

When you’re disconnecting fuel, brake, hydraulic or coolant lines, leaving ports open lets dirt, moisture and spills into sensitive systems. This Tallew kit supplies 144 red plastic caps and plugs in sizes covering AN 3, AN 4, AN 6, AN 8, AN 10 and AN 12, so you can quickly seal fittings, block hoses and protect threads while you work. The parts are molded from durable plastic intended to resist deformation and provide a consistent temporary seal across a wide temperature range.

How will this kit speed up routine repairs?

The set keeps every disconnected line immediately capped, reducing cleaning and flush time after repairs. With multiple sizes on hand you avoid searching for the right-sized plug mid-job, and the uniform red coloring makes parts easy to identify on a bench or in a tray.

• 144-piece assortment saves loading trips to the parts store.
• AN3–AN12 range covers most common automotive hose and fitting sizes.
• Bright red parts are simple to spot during disassembly and reassembly.

Are these caps and plugs reliable as temporary seals?

These caps and plugs are designed for temporary service use—blocking contaminants and limiting fluid loss while systems are open. They’re not intended as permanent pressure-rated fittings but provide a stable barrier during inspection, routing and component replacement.

• Sturdy plastic construction resists cracking and maintains shape.
• Snug friction fit helps prevent drips and entry of grit.
• Works well for brake, fuel, hydraulic and coolant line protection.

What sizes are included and how do I choose the right one?

The kit includes caps and plugs sized for AN 3, AN 4, AN 6, AN 8, AN 10 and AN 12 fittings, giving coverage for most small- to medium-diameter automotive lines. Match the cap to the outer diameter or fitting size of your hose or port for the best fit; if unsure, try the next size up to avoid overstretching the part.

• AN 3 / AN 4 — common in small coolant or vacuum lines.
• AN 6 / AN 8 — fits many fuel-return and brake hose ends.
• AN 10 / AN 12 — used on larger hydraulic or supply lines.

How should I store and re-use these caps and plugs?

Keep unused pieces in a dry container away from direct sunlight to preserve flexibility and color. Most caps can be re-used if they remain undamaged and retain their friction fit; inspect for cuts or deformation before reapplying to another service point.

• Store in original box or a small divider tray for quick selection.
• Re-use only if the part shows no stretching or cracks.
• Dispose of any pieces exposed to aggressive solvents or high heat.

Who is this for: This kit is aimed at automotive technicians, home mechanics, race teams and restoration hobbyists who need a versatile, ready-to-use supply of protective caps and plugs. If you perform fluid-line maintenance, brake work or hydraulic repairs and want to reduce contamination and cleanup time, the Tallew 144-piece set offers a practical assortment that fits most common hose and fitting sizes.
