BUSY-CORNER Vacuum Connector Assortment — 115pc Nylon 66 Heat-Resistant Tee, Reducer & Straight Fittings (Rated 240°C)

BUSY-CORNER's 115-piece Nylon 66 vacuum connector assortment is a heat-resistant automotive kit with tees, reducers and straight fittings to repair or customize vacuum hose systems up to 240°C (460°F).

This kit supplies a comprehensive selection of vacuum tubing connectors designed for automotive use, packaged in a clear PP storage box for quick access. The assortment covers three connector styles (tee, reducer and straight) across twelve commonly used sizes, letting you match or replace factory vacuum lines without hunting for individual fittings.

What types of vacuum connectors are included and why does that matter?

The collection contains three connector styles used in most vehicle vacuum systems: tee connectors for branching lines, straight connectors for inline repairs, and reducer connectors to join hoses of different inside diameters. Having all three types on hand reduces downtime and prevents improper joins that can cause leaks.

• 115 total pieces across 12 popular sizes for broad compatibility
• 5 straight sizes, 5 tee sizes, 2 reducer sizes for flexible repairs
• Organized in a transparent PP box for fast size selection

How hot can these connectors safely handle under the hood?

Each fitting is molded from Nylon 66 and tested for high-temperature stability up to 240°C (460°F), which makes them suitable for many engine bay locations where elevated temperatures occur. While heat-resistant, they should still be kept away from direct contact with extremely hot components and checked regularly for wear.

• Nylon 66 construction resists heat and mechanical stress
• Rated to 240°C (460°F) for reliable performance near hot engine areas
• Durable black finish hides grime and keeps a factory look

How do I choose the correct size and install these connectors?

Match the connector bore to your vacuum hose inner diameter and start with a test fit — the kit’s size variety makes this straightforward. Push hoses fully onto the barb, and use hose clamps or crimping where appropriate for high-pressure or critical vacuum circuits.

• Use the clear storage box to lay out sizes for quick comparison
• Ensure hoses seat fully on barbs; clamp if system demands it
• Keep reducers for adapting mismatched hose sizes without cutting existing lines

What’s included in the packaging and how is it organized?

The set is supplied in a compact transparent polypropylene (PP) box with compartmented sections so you can store and retrieve parts cleanly. Each compartment contains a pre-counted number of connectors so you can inventory or restock quickly.

• Compact clear PP storage box keeps parts visible and organized
• 12 popular sizes across 115 pieces for workshop readiness
• Lightweight, portable kit ideal for mobile mechanics or home garages
