Manifold Gauge Boot Set

This Yellow Jacket 49190 set supplies two rubber boots sized for 3 1/8 in manifold gauges. One boot is blue and the other red to match the colour coding on the gauges. The boots slip over the gauge bodies to protect the metal casing from dents and scratches during daily service work. HVAC technicians who carry manifolds in tool bags or truck compartments will find the added protection useful.

Replaces Worn Gauge Boots

The set replaces cracked, torn or missing original boots that no longer cushion the gauges. A fresh pair restores the colour-coded identification and prevents the gauge faces from contacting hard surfaces when the manifold is set down. The upgrade is worth it whenever the existing boots show visible damage or have lost their grip on the gauge housing.

Protection Capacity and Limits

The rubber boots comfortably absorb the routine knocks and drops encountered during residential and light commercial service calls. They run out of protection when a manifold suffers a severe impact that exceeds the material's cushioning ability or when the boots themselves degrade from prolonged refrigerant and oil exposure.

Questions about this item

Will the boots fit my 3 1/8 in gauges?

The set is made for 3 1/8 in gauges and includes one blue and one red rubber boot that are colour coded to match each gauge.

How do I install the boots without damaging the gauge face?

Slip each boot over the gauge body from the rear, aligning the colour coded side with the correct gauge, and press until it seats flush without forcing the lens.

When should I replace the rubber boots?

Replace them when the rubber shows cracking, hardening or loss of elasticity that lets moisture reach the gauge internals.
