Does the Walterscheid™ WE-BT Carbon Steel Angle Screw Connection require Teflon tape or anaerobic sealant for reliable sealing on the BSPT thread?

Walterscheid™ WE-BT Carbon Steel Angle Screw Connection with the BSPT thread is intended to achieve reliable sealing using either Teflon (PTFE) tape or an anaerobic sealant. The product description specifies that the BSPT external thread ensures reliable sealing when sealed with Teflon tape or an anaerobic sealant, so using one of these common sealing methods is appropriate for dependable leak-free connections.

Is the Walterscheid™ WE-BT Carbon Steel Angle Screw Connection compatible with hydraulic systems using different sealing methods on the BSPT thread (e.g., Teflon tape, anaerobic sealant, or pre-coated fittings)?

Yes — the Walterscheid™ WE-BT Carbon Steel Angle Screw Connection is compatible with hydraulic systems using different sealing methods on the BSPT thread. The connector’s BSPT external thread is explicitly designed to achieve reliable sealing with Teflon tape or anaerobic sealant (and equivalent thread-sealing materials), as stated in the product description. Its design—combining a 24° DIN 2353 socket with the external BSPT thread—allows the mechanical metal-to-metal sealing of the DIN connection to remain intact while the BSPT thread uses the chosen thread sealant to prevent leakage. Key considerations for best performance: - Use the recommended quantity and application method for Teflon tape or anaerobic sealant to avoid over-application that could interfere with thread engagement or contaminate the hydraulic circuit. - Ensure compatible sealants (hydraulic-grade PTFE tape or anaerobic compounds rated for system fluid and pressure). - Follow correct assembly torque and series selection (LL, L, S) for pressure and load requirements to preserve the 2.5:1 safety factor. - Pre-coated fittings (factory-applied sealant) are acceptable if the coating is compatible with system fluids and rated for the operating pressure. When these precautions are followed, Walterscheid™ WE-BT Carbon Steel Angle Screw Connection will provide reliable, long-lasting service with various BSPT sealing methods.
