Apopip Vacuum Tubing Elbow Connector Assortment — 8-Pack PVC Vinyl, Heat-Resistant 4 Size Pairs

Apopip 47431 is an 8-piece assortment of soft elbow vacuum tubing connectors made to replace worn or brittle automotive vacuum fittings.

If vacuum lines in your vehicle have become dry, cracked, or loose, this kit supplies a selection of soft elbow connectors in common sizes and shapes to restore secure vacuum and vent hose connections. The set includes multiple diameter combinations and both black and white color options, constructed from heat-resistant PVC vinyl to withstand under-hood conditions. Packaged for easy selection, the assortment swaps in for many OE and aftermarket part numbers to help extend the life of fuel pressure regulators, vent tubes, and other vacuum-driven components.

What sizes and shapes are included in this 8-pack?

The assortment contains four distinct diameter pairings across eight pieces, covering small-to-smaller hose transitions and straight-through fittings. That mix is chosen to match common automotive vacuum and vent tube requirements so you can find a close fit without cutting or forcing lines.

• Two pieces: 1/8" × 5/32"
• Two pieces: 1/8" × 1/8"
• Two pieces: 1/8" × 11/64"
• Two pieces: 9/64" × 5/32"

How do these connectors hold up under heat and engine bay conditions?

Each elbow is molded from durable, high-temperature PVC vinyl or a sturdy plastic compound to resist softening and premature failure from heat and oil exposure. While not intended for extreme high-temperature or pressurized systems, they are suitable for routine vacuum and vent tube duties found on most passenger vehicles.

• Heat-resistant PVC vinyl construction for everyday engine bay use
• Flexible design to reduce stress on brittle hoses
• Corrosion- and oil-resistant material for longer service life

Can these replace original equipment (OE) elbow fittings?

Yes — the assortment is sized to interchange with several common OE and aftermarket reference numbers, making them a practical field or shop replacement. They work well for replacing dry-rotted vacuum elbows and vent tube fittings on components like fuel pressure regulators, intake manifolds, and small vacuum actuators.

• Compatible with multiple interchange part numbers (e.g., some Dorman references)
• Available in black or white depending on visibility or matching needs
• User-friendly packaging for quick selection and storage

How should I choose the right elbow from the kit for my repair?

Match the internal diameters listed on the kit to the hose ends you need to join, then select an elbow whose angles and bore sizes align with the hose geometry. If in doubt, temporarily test-fit the connector on the hose; a snug, non-forced fit is ideal to prevent leaks.

• Measure both hose inner diameters before selecting a piece
• Choose the connector that allows a natural hose routing without kinks
• Replace multiple adjacent brittle fittings to avoid repeated service
