Can the Twisted coupling for pneumatic pipes and hoses straight, type B3 be used with plastic hoses without reinforcing sleeves (B12) at 60 bar working pressure?

Twisted coupling for pneumatic pipes and hoses straight, type B3 is designed for connecting copper pipes and plastic hoses and has a working pressure of 60 bar. The product description explicitly recommends using reinforcing sleeves (B12) when connecting to hoses. Therefore, using this coupling with plastic hoses without reinforcing sleeves at 60 bar is not recommended. Without the sleeve, the hose may deform or slip from the fitting under high pressure, compromising seal integrity and safety. If you must operate at 60 bar, use reinforcing sleeves (B12) specified for your hose type and size or consult the hose manufacturer for compatibility and approval.

Is Twisted coupling for pneumatic pipes and hoses straight, type B3 compatible with different hose materials at 60 bar when used with B12 reinforcing sleeves?

Twisted coupling for pneumatic pipes and hoses straight, type B3 Format: Yes. The product description specifies Straight coupling type B3 with a locking ring for connecting copper pipes and plastic hoses, with recommended use of B12 reinforcing sleeves when connecting hoses. Material is nickelâplated brass and working pressure is 60 bar. Therefore, when B12 reinforcing sleeves are used, Twisted coupling for pneumatic pipes and hoses straight, type B3 Format is compatible with different hose materials at 60 bar, provided the hoses fit the coupling dimensions and the reinforcing sleeves are properly installed.

Does Twisted coupling for pneumatic pipes and hoses straight, type B3 require specific hose diameters when used with B12 sleeves at 60 bar?

Twisted coupling for pneumatic pipes and hoses straight, type B3 Format: Based on the provided description, Twisted coupling for pneumatic pipes and hoses straight, type B3 does recommend using reinforcing sleeves (B12) when connecting to hoses, but the description does not specify particular hose inner diameters required for use with B12 sleeves at 60 bar. In practice, reinforcing sleeves are matched to the hose inner diameter to ensure a proper seal and mechanical support under the stated working pressure (60 bar). Therefore you must select B12 sleeves sized to the hose inner diameter and compatible with the coupling dimensions specified by the manufacturer. If precise diameter tolerances or sleeve-to-hose pairing data are needed, consult the manufacturerâs technical datasheet or supplier to obtain the exact compatible hose diameters for B12 sleeves with Twisted coupling for pneumatic pipes and hoses straight, type B3 at 60 bar.
