The industry uses a large number of technical abbreviations to describe dimensions, connections, pressure classes, materials and different connection types. To make it easier for you as a customer, we have collected the most common abbreviations that appear on Hydroscand's product pages and in our technical documentation.

Most abbreviations follow established industry standards and are used globally in hydraulics, pneumatics, industrial piping and hoses. This page therefore serves not only as a guide to Hydroscand's own abbreviations, but also as a useful encyclopedia for general technical abbreviations you may encounter in the industry.

This guide is particularly useful for:

• quickly interpret specifications on hoses, fittings and pipes
• understand product data on the web and in technical data sheets
• get clear explanations that help both professionals and beginners
