• The PCV & BREATHER HOSE connects the crankcase to the air cleaner, transporting blow-by gas to the air cleaner and surge tank.
• It regulates internal engine pressure and reduces emissions by recirculating harmful gases for re-combustion.

• All Rubber (Non-reinforced)
• Inner Rubber + Outer Rubber

• AEM
• FKM

Inner Diameter (I.D.): Φ7 – Φ24.5

• Excellent Oil and Heat Resistance

To withstand oil vapors generated in the crankcase and high-temperature environments, we utilize special materials with superior chemical and heat resistance, such as AEM (Ethylene Acrylic Rubber) and FKM (Fluoroelastomer). These materials prevent hose hardening and damage caused by oil vapors

• High Durability

Manufactured with a dual-layer structure (combining inner and outer rubber) or an all-rubber structure to endure engine room vibrations and external impacts. This design protects the hose from environmental factors and ensures stable, long-term performance.

• Various Specifications

Available in a wide range of dimensions with inner diameters from $\Phi$7mm to $\Phi$24.5mm, making them applicable to various vehicle models and engine specifications.

• Efficient Gas Circulation

Effectively discharges gases from inside the crankcase to maintain constant engine pressure and contributes to reducing sludge formation caused by incomplete combustion.

• Manufactured using AEM rubber, which is suitable for components requiring high durability features such as oil, fuel, ozone, and heat resistance.
• For applications requiring resistance to fuel permeation and alcohol, a dual-layer structure can be produced by extruding FKM rubber as the inner layer.
• After rubber extrusion, the mandrel molding process is applied to manufacture customized products in various shapes according to customer requirements
