Does the Nickel-plated brass four-piece with GW BSP, type A14 require Teflon tape or washers for sealing depending on thread type?

Nickel-plated brass four-piece with GW BSP, type A14 may require additional sealing depending on the thread form. For tapered BSP threads use Teflon tape or a suitable thread sealant; for cylindrical (parallel) BSP threads use a crush washer (aluminium or copper) to achieve a tight seal. The product description notes that internal BSP connections typically need such additional seals; material is nickelâplated brass and working pressure is 60 bar.

Can Nickel-plated brass four-piece with GW BSP, type A14 tolerate 60 bar working pressure without additional thread seals?

Nickel-plated brass four-piece with GW BSP, type A14 cannot be assumed to tolerate 60 bar working pressure without additional thread seals. Description explicitly states that tightness usually requires additional seals: tapered (BSPT) threads need PTFE tape or sealant; cylindrical (BSPP) threads require aluminum or copper washers. Even though material and nominal working pressure are 60 bar, proper sealing method must be applied per thread type to ensure leak-free performance and safety at that pressure.

Does Nickel-plated brass four-piece with GW BSP, type A14 require specific sealants for hoses and fittings?

Nickel-plated brass four-piece with GW BSP, type A14 does require specific sealants for hoses and fittings to ensure tightness. According to the product description, the four-way coupling with internal BSP threads (type A14) typically needs additional seals. Use Teflon tape or a suitable thread sealant on tapered (BSPT) threads. For cylindrical (BSPP) threads, use aluminum or copper washers to achieve a leak-free connection. The coupling is nickel-plated brass and rated to 60 bar, so choose sealants and washers compatible with brass and the pneumatic medium and pressure.
