Titan part 700-175 is a potentiometer cap that fits over the pressure control potentiometer on compatible sprayers. It protects the potentiometer shaft from dust, debris, and accidental adjustment while providing a finished appearance. This cap replaces the original Titan part 507748. Replacing a lost, cracked, or worn cap helps maintain accurate pressure control and extends the life of the potentiometer.

The Titan 700-175 Potentiometer Cap is a protective cover designed to fit over the pressure control potentiometer shaft on a wide range of Titan airless sprayers. It shields the delicate potentiometer from dust, moisture, and physical damage while preventing accidental adjustment during operation. This cap directly replaces the original Titan part number 507748.
A missing or damaged potentiometer cap can expose the shaft to contaminants, leading to erratic pressure control, premature wear, or potentiometer failure. Replacing it with this genuine Titan cap restores protection and ensures reliable performance.

*Replaces original Titan part number 507748. Verify with your machine's parts manual.
When replacing the potentiometer cap, these related components are often inspected or replaced at the same time.
If the cap was missing for a long time, the potentiometer itself may be contaminated or worn.
Some models use a knob that attaches over the cap; inspect for cracks or looseness.
If pressure control is erratic, the entire control assembly may need evaluation.
