PLC Fittings Overview

PLC (push-lock) fittings make fast, tool-free connections in the air system by locking onto the tube when pushed in. A worn collet or O-ring lets the fitting leak or release. Van Horn Truck Parts carries PLC fittings cross-referenced to Automann and OEM part numbers.

Match each fitting by tube OD and thread size and type for a secure, leak-free connection.

Mechanic & Fitment Specs:

  • Match by: Tube OD, thread size/type
  • Cross-references: Automann, OEM
  • Buying tip: Cut tubing square and deburr before inserting for a proper seal
