Engine Coolant Fittings
Glycol-based engine coolants are an essential component to protecting a truck's engine. Without the proper coolant, a truck's engine can start to melt and pre-maturely war down, a costly expense to repair or replace. In addition to preventing engine overheating, engine coolant also provides some lubrication for key components such as the water pump, head gasket, and cylinder and piston timing. Preventing leaks of glycol-based engine coolant is of high importance for protecting employee health and the environment. Accidental ingestion of glycol-based coolants can have adverse effects on an employee's or wildlife's health.

Brass Compression Coolant Fittings - Vibra-Lok
Parker's Vibra-Lok brass compression style transportation coolant fittings are designed to handle applications with high heat and vibration. The compression style connection of our Vibra-Lok coolant fittings provides a reliable, leak free seal even when used with glycol-based engine coolants. The sleeve cushions the coolant tubing, permitting the tubing to flex back and forth in the fitting. Parker's Vibra-Lok coolant fittings can be used in applications involving static pressure, minor surges or shock and severe vibrations or shock. Vibra-Lok fittings are available with NPTF and SAE J1926 straight threads.
