Rubber Breather Pipe Crankcase Vent Hose — Flexible, Oil-Resistant Reinforced Tubing

Crankcase pressure buildup is one of those problems that quietly causes oil leaks, seal failures, and rough idle — until you replace the worn or cracked vent hose. Whether you're doing a PCV system refresh, routing a catch can, or replacing a brittle OEM breather tube, this reinforced rubber breather pipe gives you a reliable, flexible solution without the guesswork of sourcing an exact OEM part.

Each length is cut from reinforced rubber tubing with a smooth inner bore and a fabric-reinforced outer wall for added burst resistance. Available in six inner diameter sizes — 6×10mm (≈1/4"×3/8"), 8×13mm (≈5/16"×1/2"), 10×16mm (≈3/8"×5/8"), 12×18mm (≈15/32"×11/16"), 14×20mm (≈9/16"×25/32"), and 16×22mm (≈5/8"×7/8") — and in cut lengths of 1m (≈39"), 2m (≈79"), 3m (≈118"), and 4m (≈157"). Color options are Black and Blue.

Typical applications include crankcase ventilation hose replacement on passenger cars and light trucks, oil catch can inlet and outlet lines, air compressor drain tubing, and general-purpose engine bay vent routing on motorcycles and ATVs. The flexible construction makes it easy to route around tight bends without kinking — a common issue with rigid plastic OEM breather tubes.

🔧 Universal Fit: Not vehicle-specific. Match the inner diameter (ID) to your fitting or vent port OD. Use a hose clamp for a secure, leak-free connection. See variant options for available sizes.

✅ Key Features of These Rubber Crankcase Vent Breather Hoses

  • 🛡️Oil-Resistant Inner Bore — Formulated to resist oil mist, vapors, and light oil contact typical of crankcase ventilation and PCV system applications.
  • 🔩Fabric-Reinforced Wall — The woven reinforcement layer adds burst resistance and helps the hose hold its shape under vacuum or pressure, reducing collapse risk in vent lines.
  • 📐Six ID Sizes Available — From 6mm to 16mm inner diameter, covering the most common crankcase vent hose sizes for cars, motorcycles, and small engines without adapters.
  • ✂️Cut-to-Length Flexibility — Order 1m, 2m, 3m, or 4m to match your exact routing path. Cuts cleanly with a utility knife for a flush, clamp-ready end.
  • 🌡️Engine Bay Temperature Tolerance — Suitable for the elevated ambient temperatures found in typical engine bays; generally rated for continuous use up to approximately 120°C (248°F).
  • 🎨Black or Blue Finish — Black blends with factory engine bay aesthetics; Blue offers a visible contrast for custom builds or easy identification in complex hose routing.

⚠️ Confirm your fitting OD before ordering. Inner diameter must match your vent port or barbed fitting outer diameter for a proper seal. When in doubt, contact us to confirm compatibility.

❓ Frequently Asked Questions

How do I choose the right hose size?

Match the inner diameter (ID) to your fitting or nipple OD. For example, a 10mm nipple typically pairs with the 10×16mm hose. Always measure your fitting before ordering. If you're between sizes, size up for a snug push-fit or use a clamp to secure a slightly looser fit.

What length should I order?

Measure the routed path from your crankcase vent port to the catch can or air intake, then add 10–15% for bends and routing curves. Available in 1m (≈39"), 2m (≈79"), 3m (≈118"), and 4m (≈157") cuts. For most passenger car applications, 1–2m is generally sufficient.

Is this hose oil-resistant?

Yes. The hose is constructed from oil-resistant rubber, making it suitable for crankcase ventilation, PCV systems, and other applications where oil mist or vapors are present. It is not intended for direct fuel immersion or continuous submersion in petroleum-based fluids.

Can I use this hose in a high-heat engine bay?

This hose is designed for engine bay use and can generally handle the elevated ambient temperatures typical of crankcase vent applications — typically up to approximately 120°C (248°F) continuous. Keep the hose away from direct contact with exhaust manifolds or headers. For sustained extreme heat exposure, a silicone hose may be more appropriate.

What fitting or thread standards does this hose work with?

This is a push-fit / clamp-on hose with no internal threading. It is compatible with standard barbed fittings, nipples, and vent ports sized to match the listed inner diameters (6mm, 8mm, 10mm, 12mm, 14mm, or 16mm). A hose clamp is recommended for a secure, leak-free connection in pressurized or vacuum applications.

What vehicles or equipment is this compatible with?

This is a universal-fit hose — not vehicle-specific. It is commonly used on cars, motorcycles, ATVs, small engines, air compressors, and industrial equipment wherever a flexible rubber vent or oil drain hose is needed. Verify the inner diameter matches your application's fitting OD before ordering.

How do I cut the hose to the length I need?

A sharp utility knife or dedicated hose cutter gives the cleanest cut. Score around the circumference first, then cut through in one pass to avoid a ragged edge that could affect sealing at the fitting. The reinforced wall cuts cleanly without fraying.
