Supreme Fittings

Quapus sa srl by Supreme fittings has been operating in the water circulation market segment for over 40 years with applications in the following sectors:

  • Irrigation
  • Water supply
  • Plumbing
  • Industrial
  • Water treatment

The connection is a weak point therefore the fitting must be stronger, more reliable, more flexible than the line itself. Our products are designed and manufactured with innovative operating systems to obtain:

- easy and fast installation
- ability to compensate pipe dimensional anomalies, ovalizations, pipes scratchs
- hydraulic seal in conditions of use under pressure and vacuum.

These criteria have always been the basis for the study, development and realization of the Supreme fittings lines.

The use and performance of the water pipes are so optimized and the assembly and maintenance costs are reduced.

The competitive price of the single product offered is another qualifying factor of the proposal to the market. We are therefore able to offer innovative, reliable and economic technical solutions. We always pay maximum attention to the specific customers needs. Our before and after sales service is organized for customer satisfaction and profitability. The large number of complementary products allows you to optimize warehouse management and reduce administrative costs.
