Is the FFORX duct cleaning nozzle compatible with flat seal couplings with a 6 mm (1/4") sealing ring?

Yes. The FFORX duct cleaning nozzle Format is compatible with flat seal couplings that use a 6 mm (1/4") sealing ring. The product description specifies it is designed for cleaning pipes with flat seal couplings with a sealing ring of that size, so it will fit and form the correct seal for operation.

Can the FFORX duct cleaning nozzle reliably form a seal with flat seal couplings using a 6 mm (1/4") sealing ring?

Yes. The FFORX duct cleaning nozzle is designed specifically for pipes with flat seal couplings using a 6 mm (1/4") sealing ring. Its geometry and sealing lip align with flat-coupling profiles to compress the 6 mm ring evenly, creating a reliable pressure seal for cleaning operations. For best results ensure the sealing ring is undamaged, correctly seated, and the coupling faces are clean and aligned; under those conditions the FFORX duct cleaning nozzle will form a dependable seal.

Does the FFORX duct cleaning nozzle fit flat seal couplings with a 6 mm (1/4") sealing ring?

Yes. The FFORX duct cleaning nozzle is designed for pipes with flat seal couplings that use a 6 mm (1/4") sealing ring, so it will fit those couplings.
