Is the Flanged connection 4-hole 90Â° with GW BSP made of aluminum compatible with standard hydraulic pump ports and supplied with screws, washers and an O-ring?

Yes. The Flanged connection 4-hole 90Â° with GW BSP made of aluminum is compatible with standard hydraulic pump ports: it features internal BSP thread and a flange with a pitch diameter for 4 holes from 30 mm to 55 mm, designed specifically for hydraulic pump connections. It is supplied as standard with a set of screws, washers and an O-ring. Operating temperature range: -20Â°C to +100Â°C.

Can the Flanged connection 4-hole 90Â° with GW BSP made of aluminum withstand hydraulic system pressures and temperature range (-20Â°C to +100Â°C)?

Flanged connection 4-hole 90Â° with GW BSP made of aluminum can be used in hydraulic systems within the stated operating temperature range (-20Â°C to +100Â°C) because its material and specified temperature rating cover that range. However, whether it can withstand system pressures depends on the specific pressure rating, which is not provided in the description. Aluminum flanged fittings are commonly used for moderate hydraulic pressures, but their allowable working pressure is lower than steel. For safe use, verify the productâs maximum pressure rating from the manufacturer or datasheet and ensure compatibility of the O-ring material with hydraulic fluid and temperature. If system pressures are high or cyclic/impact loads are expected, consider a higher-strength material or validated pressure testing.

Does the Flanged connection 4-hole 90Â° with GW BSP made of aluminum require special mounting torque for the supplied screws?

Flanged connection 4-hole 90Â° with GW BSP made of aluminum does not explicitly require a special mounting torque specified in the provided description. However, because the part is aluminum and is supplied with screws, washers, and an O-ring for hydraulic pump connections, best practice recommendations apply: - Use the manufacturerâs recommended torque if available (check product documentation or supplier). - If no specific torque is provided, apply moderate, controlled torque to avoid stripping the aluminum threads or deforming the flange. Typical torque ranges for small aluminum flange screws (depending on screw size and grade) are often lower than for steel. for example, roughly 20â60% of equivalent steel torque tables. - Tighten screws progressively and in a cross/star pattern to ensure even compression of the O-ring and an even flange seat. - Use washers as supplied to distribute load and protect the aluminum. - If threads are aluminum into steel bolts, consider threadlocker or anti-seize depending on service conditions and follow appropriate torque derating. - After initial installation, recheck torque after first operation or run-in, especially in hydraulic systems and at varying operating temperatures (-20Â°C to +100Â°C). In summary: no special torque is stated in the description, but use conservative, evenly applied torque appropriate for aluminum components and follow any supplier guidance when available.
