61225119- ORDERING DATA.pdf

This is a Technical Ordering Specifications document for a flat sealing gasket component. The gasket is manufactured from soft copper (material designation CU) to provide leak-proof connections under high hydraulic pressure and conforms to the DIN 7603-A flat gasket standard. The part number is 1034, with dimensions of A22x27 (22 mm inner diameter for M22 threaded fittings and 27 mm outer diameter). The gasket thickness is typically either 1.5 mm or 2.0 mm depending on specific assembly requirements. The copper material can withstand temperatures up to 300°C and creates a static seal by molding into surface irregularities when tightened.

The procurement section specifies that the part is available through Palfinger as OEM supply via authorized Palfinger dealers to ensure compatibility with specific crane models' hydraulic blocks. Industrial alternatives are available from standardized retailers including Misumi and Keller & Kalmbach, with the gasket also commonly used in WABCO air systems and heavy machinery applications. Installation notes indicate that copper sealing rings are single-use components and should be replaced each time the associated bolt or bleed valve is loosened to maintain proper sealing integrity.
