Can the Twisted Bulkhead Coupling for Pneumatic Pipes and Hoses, Type B4, be used without a reinforcing sleeve (B12) on flexible hoses at pressures up to 60 bar?

Twisted Bulkhead Coupling for Pneumatic Pipes and Hoses, Type B4: Although the B4 fitting is rated to withstand working pressures up to 60 bar and is constructed from high-quality nickel-plated brass, the product description explicitly recommends using reinforcing sleeves (B12) for hose connections to enhance stability and extend service life. Therefore, while the fitting itself can handle up to 60 bar, using it on flexible hoses without a reinforcing sleeve is not recommended—especially under high pressure or demanding applications—because the sleeve improves hose support, prevents deformation or blowout at the fitting, and prolongs safe operation. If you must omit the sleeve, consult the hose manufacturer’s specifications and perform appropriate pressure and safety verification for your specific hose type and application.

Is the Twisted Bulkhead Coupling for Pneumatic Pipes and Hoses, Type B4, compatible with stainless steel braided hoses using B12 reinforcing sleeves?

Yes. The Twisted Bulkhead Coupling for Pneumatic Pipes and Hoses, Type B4 is compatible with stainless steel braided hoses when B12 reinforcing sleeves are used. The B4 fitting is designed for secure connections between pipes and hoses, is made of nickel-plated brass for corrosion resistance and strength, and withstands working pressures up to 60 bar. The recommended B12 reinforcing sleeves enhance hose stability and service life, making them suitable for use with stainless steel braided hoses in demanding pneumatic and hydraulic applications.
