Parker 43 series alternative: Intertraco K series hydraulic fittings
Parker 43 series alternative: the Intertraco K series
The Parker 43 series is a widely used range of crimp fittings for medium pressure hydraulic applications. Van de Calseyde supplies the Intertraco K series as a direct replacement for all common types in the Parker 43 family.
The K series covers the same connection types, thread standards and sizes as the Parker 43, and is fully compatible with standard crimping equipment and hoses in the medium pressure class.

Why choose the Intertraco K series?
The Intertraco K series is manufactured by Intertraco (Italia) S.p.A., an Italian hydraulic fitting manufacturer with over 50 years of experience. Van de Calseyde is the exclusive Belgian distributor for Intertraco and supplies the K series from stock in Ghent.
The K series is fully validated in combination with the Intertraco hose range, including the SK216S. This means you work with a validated hose-and-fitting combination, without depending on Parker-specific crimping machines or tooling.
