177mm Extra Long Silicone Sealant Nozzles C3 310ml Cartridges 10pk

Sealants and Tools direct 177mm Extra Long Nozzles C3 and 310 ml Cartridges Pack of 10

Code: NOZLONG

Overview:

Sealants & Tools Direct 177mm Extra Long Nozzles are designed to give you better reach and control than standard sealant nozzles, making awkward application jobs far easier. Supplied as a pack of 10, these long nozzles feature an extra-wide internal shaft to help the flow of thicker sealants and adhesives, reducing drag and making it easier to run a consistent bead. The base is also slightly larger and more robust than a standard nozzle, helping it sit more securely on the cartridge for improved stability during use.

They’re ideal when a normal nozzle is simply too short or blocks your view of the joint, such as sealing under window sills, behind taps and pipework, around sink edges, behind radiators, inside cupboards, around frames and trims, or into deep gaps where access is tight. The extra length keeps the application point further away from the gun, giving you better visibility of the bead as it’s laid down and helping you apply cleaner, more accurate finishes especially in confined spaces or when working at awkward angles.
