Is the Aluminum washer, type RA compatible with Banjo screws and what sizes are available?

Yes . the Aluminum washer, type RA is compatible with Banjo screws. Description: "Aluminum washer intended for Banjo screws. Material: aluminum." That indicates the washer is specifically designed for use with Banjo screws, so it will fit and function as their mating washer. Available sizes: the description does not list specific dimensions or size options. To get exact sizes (inner diameter, outer diameter, thickness, and compatible Banjo screw sizes), please check the product datasheet or contact the supplier/manufacturer for size variants and fitment details.

Can the Aluminum washer, type RA be used with stainless steel Banjo screws without causing galvanic corrosion?

Short answer: Yes, but with conditions. Aluminum washer, type RA can be used with stainless steel Banjo screws without a high risk of galvanic corrosion in most typical environments because stainless steel is less noble than many other metals and aluminum forms a protective oxide layer. However, avoid prolonged exposure to aggressive electrolytes (sea water, salt spray, humid coastal or industrial atmospheres) where galvanic coupling may accelerate aluminum corrosion, especially at crevices or under load. To minimize risk: ensure good drainage and ventilation, avoid trapped moisture, use an insulating barrier (polymeric or non-conductive coating) between Aluminum washer, type RA and the stainless screw, or apply a compatible corrosion-inhibiting grease. For critical or long-term outdoor/marine applications consider selecting a sacrificial or more compatible material or consult corrosion testing.

What torque specification is recommended when tightening Aluminum washer, type RA with Banjo screws?

For Aluminum washer, type RA used with Banjo screws, a conservative recommended tightening torque is 2.0â3.0 NÂ·m (17â26 inÂ·lb). Rationale: aluminum washers are softer than steel and can deform or gall if over-torqued; the lower torque range protects the washer and banjo fitting while providing sufficient clamp load for fluid/pressure sealing. If the application uses steel bolts, softer aluminum washers can also benefit from a thin layer of anti-seize or a torque-limiting washer to reduce galling. Always follow the Banjo screw manufacturer's torque spec if provided; if a specific bolt grade or critical pressure application is involved, verify with the equipment manufacturer or perform a torque/pressure test.
