NPF & LPF Manifold Gauges

NPF & LPF Manifold Gauges are high-quality, professional-grade tools designed for accurate pressure measurement and efficient servicing of HVAC and refrigeration systems. Engineered with precision and durability in mind, these manifolds are ideal for technicians who require reliable performance during charging, testing, and maintenance operations.

The aluminum and brass manifold variants are built to meet different application needs while maintaining consistent quality standards. The lightweight aluminum manifold features an extruded body for strength and portability, while the forged brass manifolds provide enhanced durability and leakproof reliability. Both options are designed with user convenience and long-term performance in mind.

Equipped with large, easy-to-read gauges (3-1/8″ NPF® or 2-1/2″ LPF™), these manifolds ensure clear visibility and accurate readings. The gauges come with color-coded refrigerant scales and protective boots, making them easy to use and resistant to damage. Advanced features such as No Pointer Flutter® (NPF) and Limited Pointer Flutter™ (LPF) technology enhance reading stability and precision.

These manifold gauges also include high-quality hoses and fittings, ensuring safe and efficient operation. With features like EZ-Turn anti-blowback fittings, ball valve options, and fast-flow charging capabilities, they provide flexibility for various HVAC tasks.
