EN 12115 Explained: Rubber and Thermoplastic Hoses for Liquid or Gaseous Chemicals

EN 12115 is the European specification for rubber and thermoplastic hose assemblies that carry liquid or gaseous chemicals. It defines two types based on duty — one for delivery, one for suction and delivery — four grades based on conductivity and resistance, and requirements for construction, dimensions, performance, identification and storage. This guide walks through

Pressure vs. Temperature Derating: How to Read Air Hose Ratings

An air hose pressure rating is not one fixed number. It is a value established at a reference temperature of about 23 °C (73 °F), and the safe pressure falls as the hose runs hotter or colder than that reference. Reading one correctly means separating the working pressure a hose is built to carry from
