Description
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.

Solid Big Blue 10" housing for efficient cold water filtration
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.
Main advantages
- possibility of connecting housings in series,
- high device efficiency,
- blue sump protects the cartridge against photosynthesis,
- compatible with most 10" Big Blue® cartridges available on the market,
- housing equipped with an air bleeder,
- housing and head made of high-quality materials.
Application
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.
- domestic water installations,
- industrial water installations,
- laboratory industry,
- wineries.
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.
Construction and functionality
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.
Compatibility with cartridges
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.

Questions
Which cartridges does this Big Blue 10" housing fit?
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.
Is this housing suitable for cold or hot water?
The housing is designed for cold water filtration. The operating temperature range is from 2 to 45°C.
What is the function of the air bleeder?
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.
Why are there 2 O-rings under the head?
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.
Can the housing be connected in series with other housings?
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.
Where is this housing most often installed?
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.
Does the blue sump have a practical purpose?
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.
What devices can this housing protect when used with the proper cartridge?
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.
What materials are the housing and head made of?
Both the colored housing and the head are made of PP, i.e. polypropylene. The O-ring seals are made of NBR.
