Is leak detection spray safe with A2L?

Use a foaming agent free of ammonia and compounds that corrode copper/brass. With flammable refrigerants (e.g. R32, R290), use detection according to procedure and check the product's approval.

Which flux for brazing copper in refrigeration?

For copper-to-copper brazed joints with CuP rod, flux is usually not needed; flux is required when brazing copper to brass/steel. Choose according to the type of braze and materials.

Why use assembly grease for service connections?

A thin layer of compatible assembly grease on O-rings and threads makes assembly easier, improves sealing and protects the seals from damage during tightening.

About this category: Preparaty serwisowe

In this subcategory you will find products that support the installation and servicing of refrigeration systems: foaming leak detectors for flared and brazed joints, fluxes and pastes for brazing copper, lubricants for O-rings and service connections, and other auxiliary preparations. They are selected to suit the specific stage of work and the system's materials.

When selecting, pay attention to compatibility with the refrigerant and the material (copper, brass, aluminium) as well as approval for use with flammable A2L/A3 refrigerants — a foaming leak detector must not contain ammonia or substances that corrode copper.
