10" BB housing mainly used for water inlet, compatible with 10" Big Blue cartridges.
The BIG BLUE 10" 2 x O-RING PIPE BODY is a durable filter housing for cold water, designed to work with Big Blue 10" cartridges. It works well as an efficient water filter at the point where the installation enters the building, as part of a larger water filtration system, and in systems supporting water treatment in homes and professional applications. The two-part construction, 2 O-ring seals, air bleeder, and 1" thread make safe operation and matching the right filter cartridge to the installation’s needs easier.

Model FH10B1 is a Big Blue 10" pipe housing designed for use in installations requiring high flow efficiency. The construction consists of two parts: a blue sump and a head with a 1" thread. This format is widely used where standard housings are insufficient and the filtration system must effectively protect the installation and connected devices.
The housing can operate as a single filtration stage or as part of a more advanced setup. Thanks to the option of connecting housings in series, it is easy to configure a system matched to the type of contaminants and the expected filtration result.
The 10" BB housing is mainly used at the water inlet and can be installed on the pipe supplying cold water to a house or apartment. Due to its high capacity, it is also suitable for more demanding working environments.
When used with the appropriate filter cartridge, the housing helps protect installation and utility devices from the buildup of various types of contaminants. It works well before devices such as a water softener, iron remover, pressure tank, or boiler, supporting their protection and extending the service life of the entire installation.
The two-part design includes the sump and the head, which makes installation and later servicing easier. The use of two O-rings under the head improves the tightness of the connection, which is very important in daily operation of the filtration system.
The blue sump reduces the effect of light on the filter cartridge. This is especially important when the housing is installed in a place exposed to sunlight, because protecting the cartridge from the photosynthesis process helps maintain better filter operating conditions.
An additional convenience is the air release valve. It allows air trapped in the filter to be released after cartridge replacement, which makes restarting the system after service easier and improves ease of use.
The housing is intended for cold water filtration. Before selecting a cartridge, it is worth matching its type to the type of contaminants and the installation location, because the effectiveness of installation and device protection depends on the cartridge used.
The housing is compatible with a wide range of 10" Big Blue® cartridges. These include mechanical, specialty, and carbon cartridges available on the market. This makes it suitable both for pre-filtration of sediment and for more specific applications within a larger water treatment system.
Although this model is not a reverse osmosis filter element, osmosis filter, or reverse osmosis system, it can effectively work as a preliminary protection stage for the installation supplying other filtration devices, if the configuration of the entire system requires it.

The model is compatible with most 10" Big Blue® cartridges. Mechanical, specialty, and carbon cartridges can be used, as long as they match the Big Blue 10" format.
The housing is designed for cold water filtration. The operating temperature range is from 2 to 45°C.
The air bleeder allows air trapped in the filter to be released, especially after cartridge replacement. This makes restarting the system easier and improves ease of use.
Two O-rings increase the tightness of the connection between the head and the sump. This is especially important in systems operating regularly and at higher flow rates.
Yes. One of the advantages of this model is the possibility of connecting housings in series, which allows a multi-stage water filtration system to be built.
It is most often installed at the water inlet to a house or apartment, on the pipe supplying cold water. It can also be used in industrial, laboratory, and winery installations.
Yes. The blue sump protects the cartridge from light exposure and reduces the risk of photosynthesis-related effects, which is especially important in sunlit locations.
With the right cartridge selected, the housing can support the protection of devices such as a water softener, iron remover, pressure tank, or boiler, reducing the buildup of contaminants in the installation.
Both the colored housing and the head are made of PP, i.e. polypropylene. The O-ring seals are made of NBR.
