Frequently Asked Questions
- How do I choose the right fitting size? The thread size must exactly match the thread on the pipe or fitting it connects to - the abbreviations FF (female-female thread) and MF (male-female) in the name indicate the thread type on each side.
- Is sealing material needed during installation? Yes, PTFE tape or hemp fiber with sealing paste is typically used on threaded joints to ensure a perfectly tight seal.
- Must installation be carried out by a professional? A simple threaded connection can be handled by a competent DIYer, but for work on an already functioning system (especially gas), we recommend calling in a plumber/heating technician who can also verify the joint's tightness.

“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
