Dorman 46863 PCV Valve Hose Assembly — Rubber, 4.5 in., 10mm ID

The Dorman 46863 is a replacement PCV hose assembly designed to restore proper positive crankcase ventilation to your engine. A cracked, brittle, or leaking PCV hose allows unmetered air into the intake system, disrupting the air-fuel mixture and accelerating engine wear. This rubber hose assembly — also referred to as a PCV tube, PCV tube connector, or PCV grommet — is made from quality rubber material engineered to resist the cracking and brittleness that cause original equipment hoses to fail over time.

Key Features:

• Constructed from durable rubber for long-lasting flexibility and resistance to cracking
• Overall length: 4.5 in. (114.5 mm)
• Both hose ends feature a 0.394 in. (10 mm) inside diameter for a secure, leak-free connection
• Wall thickness: 3 mm for added durability
• Straight tube shape for straightforward installation
• Package includes 1 PCV hose assembly

Restoring a healthy crankcase ventilation system helps maintain smooth engine performance and long-term engine health. Fits select 2009–2019 Nissan and 2013–2019 INFINITI models.
