Is the Angle block type "L", black galvanized steel compatible with hoses for 3000 bar work or limited to 1000 bar with metal-rubber seals?

Angle block type "L", black galvanized steel is designed for a maximum working pressure of 3000 bar. However, when using a metalârubber seal the maximum working pressure is limited to 1000 bar. Therefore compatibility with hoses for 3000 bar work depends on the seal type used: with appropriate highâpressure (nonâmetalârubber) seals and matching hose/pump fittings, it is suitable for 3000 bar; with metalârubber seals it is limited to 1000 bar. Ensure the hose, connectors and seals are rated for 3000 bar and that the internal cone 120Â° and 1/4" BSP connections are compatible.

Can Angle block type "L", black galvanized steel be used with non-metal seals to safely handle 3000 bar?

No. Angle block type "L", black galvanized steel specifies a maximum working pressure of 3000 bar only when using a metal-rubber seal; the note states the maximum working pressure when using a metal-rubber seal is 1000 bar. Since non-metal seals are not rated for the higher pressure in the description, using non-metal seals would not be safe for 3000 bar. Use the manufacturer-recommended metal-rubber sealing arrangement or consult the manufacturer for approved sealing options and pressure ratings.

Can Angle block type "L", black galvanized steel maintain leak-free connections at 3000 bar without metal-rubber seals?

No. Angle block type "L", black galvanized steel as described cannot reliably maintain leak-free connections at 3000 bar without metal-rubber seals. The product spec itself clarifies that the maximum working pressure when using a metal-rubber seal is 1000 bar, implying that the 3000 bar rating presumes a different or special sealing arrangement not provided by simple metal-rubber seals. Since the connection sealing is an internal cone 120Â° and the fittings are 1/4" BSP with a 5 mm flow diameter, achieving a leak-tight joint at extreme pressures (3000 bar) requires specialized high-pressure sealing methods (e.g., hardened cone/socket surfaces, precision-machined metal-to-metal seals, or approved high-pressure ferrules/soft seals) and validated testing at that pressure. Standard black galvanized steel components and a 120Â° cone without the specified high-pressure sealing elements are unlikely to withstand 3000 bar without leakage or failure. For safe operation at 3000 bar, use components and seals explicitly rated and tested for that pressure and follow manufacturer guidance and industry high-pressure standards.
