Product Details

The Dorman 493-021 is a hard vacuum tubing connector restrictor designed for 3/16 inch vacuum lines. This precision-engineered component is used in automotive vacuum systems to regulate vacuum flow and maintain proper system pressure.

Key Features:

  • 3/16 inch diameter fitting for standard vacuum tubing
  • Hard plastic construction for durability and heat resistance
  • Restrictor design controls vacuum flow rate
  • Direct replacement for worn or damaged OE vacuum connectors
  • Essential for maintaining proper engine vacuum system operation

Vacuum restrictors are critical components in emissions control systems, EGR systems, and other vacuum-operated engine functions. This Dorman replacement part restores proper vacuum signal strength and prevents vacuum leaks that can cause rough idle, poor fuel economy, and check engine lights.
