Learn more about one of Orscheln Products’ largest product offerings – fluid level indicators. Orscheln Products was originally founded on the creation of the first overcenter parking brake, but since then we have expanded our lines to offer more products such as our fluid level indicators. Orscheln Products is known for our patented Twist2Lock fluid level indicator line which can be used in both engine and transmission applications. What makes Orscheln Products’ Twist2Lock fluid level indicators stand out from the crowd is the fact that the locking cap prevents leaks and eliminates loose or lost sticks caused by vibration, while offering an increased accuracy of fluid level readings. Orscheln fluid level indicators come already calibrated, making it easy for customers to install in many different vehicles.
