The UBC tank cleaning nozzles are made entirely of stainless steel, with the shaft mounted on a double ring of steel balls, allowing use in any position. The internal and external surfaces are machined and deburred, and undergo meticulous finishing cycles to achieve a predefined surface roughness designed to minimize the risk of contamination from bacterial growth. Their primary application is in cleaning canisters and tanks in the food industry, although they can also be used in various other applications.
The UBC cleaning nozzle is typically supplied with a female threaded connection or a clip-on connection but is also available upon request with a weld-on connection, NPT connection, or tri-clamp fittings (note that with this configuration, the device cannot be ATEX certified).
Starting in 2025, all UBC cleaning heads we manufacture will be certified for food contact in accordance with Framework Regulation 1935/2004 and Regulation 2023/2006. Upon request, they can also be ATEX certified.
UBC M007 B31BEG | UBC M023 B31DEB
This group of cleaning nozzles comprises the smallest models in the range, primarily used for cleaning small industrial ovens.
These two devices are made of machined steel and designed with similar geometries, differing only in overall size. The smaller model features a BSP threaded connection, while the larger one comes with a BSPT connection. An NPT connection is also available upon request.

Models with clip connections are available on request. Please check the dimensions in the table below.

where:
– xxxx is the capacity (see table below);
– MM is the material (B31 for AISI 316L s.s.);
– x is the spray coverage (B = 180° down; C = 270° up; D = 270° down; E = 360°);
– C or D identify the clip connection (instead of the “G” for Female BSP thread connection).
