Is the Flanged 4-Hole Connection, Carbon Steel, DIN 2353 compatible with standard 24° DIN 2353 fittings and available in all hole pitch diameters from 35 mm to 55 mm?

Flanged 4-Hole Connection, Carbon Steel, DIN 2353 Format Yes. The flanged connection features an external metric connection thread with a 24° DIN 2353 socket, making it compatible with standard 24° DIN 2353 fittings. It is also available in hole pitch diameters ranging from 35 mm to 55 mm, covering the specified size range.

Can the Flanged 4-Hole Connection, Carbon Steel, DIN 2353 withstand operating pressures typical for hydraulic pump systems without additional reinforcement?

Flanged 4-Hole Connection, Carbon Steel, DIN 2353 Format Yes — in general the Flanged 4-Hole Connection, Carbon Steel, DIN 2353 Format is engineered to withstand typical operating pressures found in hydraulic pump systems without additional reinforcement, given normal service conditions and correct installation. Key points supporting this: - Design: Compact flanged 4-hole configuration with DIN 2353 24° socket and external metric thread provides a proven, pressure-tight mechanical interface widely used in hydraulic applications. - Materials and coating: High-quality carbon steel with galvanized coating offers the strength and wear/corrosion resistance required for standard hydraulic pressures. - Seal and hardware: Supplied O‑ring plus full set of screws and washers ensures correct preload and a leak-free joint when torqued to specification. - Temperature range: Operational between −20°C and +100°C, covering typical hydraulic fluid temperatures without compromising elastomeric seals or material properties. Caveats: Actual pressure capacity depends on flange size (hole pitch 35–55 mm), bolt grade and torque, O‑ring material, mating component ratings and system peak pressures (shock, pulsation). For high-pressure, pulsating, or safety‑critical systems verify component pressure ratings, perform appropriate torque and assembly procedures, and consult manufacturer specifications or engineering calculations.
