Can the Twisted coupling for pneumatic pipes and hoses with BSP female thread, type B2 be used with plastic hoses without reinforcing sleeves (B12) at 60 bar?

No . the Twisted coupling for pneumatic pipes and hoses with BSP female thread, type B2 should not be used with plastic hoses without reinforcing sleeves (B12) at 60 bar. Although the coupling is rated to 60 bar, the product description explicitly recommends using reinforcing sleeves when connecting plastic hoses. Reinforcing sleeves provide the necessary radial support to prevent hose deformation, extrusion, or blowout under high pressure. Without a sleeve, a plastic hose is at risk of slipping out of the ferrule, collapsing under the clamp, or failing at the connection, creating a serious safety hazard. Use the B12 reinforcing sleeve with the Twisted coupling for pneumatic pipes and hoses with BSP female thread, type B2 for safe, reliable operation at the specified working pressure.

The product description specifies itâs designed for connecting copper pipes and plastic hoses and recommends using reinforcing sleeves (B12) when connecting to hoses. Made of nickel-plated brass and rated to 60 bar, it can be used with plastic hoses provided you fit the B12 sleeves to reinforce the hose ends and ensure a secure, pressure-rated seal.
