Air Conditioner Charging and Testing Manifolds
Monitor refrigerant pressure with analog gauges when servicing air conditioning systems. All manifolds have double O-ring piston valves. Manifolds with sight glass allow you to view liquid levels.
Replacement gauges are sold separately.
Optional gauge cover sets (sold separately) include one blue and one red gauge cover. They are not for use with the manifolds for R-410A refrigerant.

Digital Air Conditioner Charging and Testing Manifolds
Monitor refrigerant pressure on an LCD when servicing air conditioning systems. This manifold automatically calculates how much refrigerant is needed in a system based on measurements taken with its thermocouples.

Pressure Recording Film
Create an instant, permanent image of pressure distribution and magnitude. These sheets of film help you identify uneven pressure that can lead to leaks and stress fractures. Use them between any two surfaces that touch each other, such as bolted joints, welding fixtures, and jigs. Tiny capsules within the film burst at specific pressure levels, causing the film to change color. This produces an instant map of pressure variation, similar to a heat map. For a custom size, cut the film with scissors.
0.008" thick film includes two 0.004" thick sheets that must be used together.
Pressure variance analysis kits include a sheet of pressure film and instructions on how to send your film to the manufacturer for analysis. The manufacturer runs the analysis through specialized software. This software gives you more accurate results than the color correlation manual. Within a few days of sending your sample in, you’ll receive an email with a full report on the force distribution and magnitude.
Use a color correlation manual (sold separately) with pressure film to determine the magnitude of the pressure measurements. The manual includes best practices and color correlation charts to help you match the colors on your film readout to the correct values.
A color sample pack includes a color correlation manual and one 3" × 4" piece of film in each of these pressure ranges: 28-85, 70-350, 350-1,400, 1,400-7,100, and 7,100-18,500 psi.
