Although both T-Type Strainers and Y-Type Strainers perform similar functions within pipeline applications, each one has their own distinctive set of qualities that make each one uniquely different. While both are effective industrial strainers for removing dirt from fluid systems and protecting your valuable downstream equipment to prolong its life expectancy and usability, it is useful to know the differences between the two when selecting your strainer filter.
Scott Miller of BM Engineering explains that Y-Type Strainers are used predominantly for liquid applications to protect downstream equipment from particles, including; dirt that may otherwise impact performance if left to settle and build up.
Scott Miller goes on to explain, most Y-Type industrial strainers can also work effectively in steam applications, as well as applications that deal with inert gases or air.
Y-Type Strainers can be fabricated to accommodate specific application requirements, however, the vast majority of Y-Type Strainers are non-customisable as standard. BM Engineering stock and supply a range of Y-Type Strainers in sizes from 1/4 to 10”. This range of Y-Type Strainers can be manufactured in a variety of materials, including cast iron and steel, bronze and AISI 316L stainless steel; with a screwed or bolted cover for screen access to ensure that process fluid is effectively drained.
Y-Type Strainers offer a variety of benefits to pipeline applications, including;
Scott Miller from BM Engineering explains that a T-Type Strainer is most commonly a custom fabricated industrial strainer, that is manufactured from pipe materials. This allows the T-Type Strainer to offer unique features, such as quick-opening style covers or the addition of a ventilation port and differential pressure taps.
Scott Miller goes on to explain that T-Type Strainers can also offset the inlet and outlet by 90 degrees, to form an elbow-shaped strainer. Scott Miller from BM Engineering explains that by using an elbow-shaped strainer, this can benefit applications with space constraints.
T-Type Strainers are applicable to all types of steam, water, oil and air systems. They are available in sizes DN15 to DN100. However, as this strainer type is fabricated; this can result in extended lead times, rather than an off-the-shelf solution of a Y-Type Strainer.
T-Type Strainers offer a variety of benefits to pipeline applications, including;
Scott Miller from BM Engineering explains that in order to choose the correct industrial strainer type, it is important to focus on the needs of your business. If you are looking for a cost-effective straining solution from an industrial strainer that offers flexibility; a Y-Type Strainer may be the best option.
However, a T-Type Strainer would be better suited if your pipeline application deals with more viscous fluids that need to be transferred at higher velocities, or a strainer that has a higher flow capacity.
BM Engineering Supplies stock and supply both Y-Type Strainers and T-Type Strainers from Valstream ADCA. As the UK’s premier distributor of Valstream ADCA products; BM Engineering can provide businesses throughout the UK with the full range of ACDA strainers, including the IS16F cast iron Y-Type Strainer; which is perfectly suited to dealing with non-dangerous fluids within pipeline applications.
Arguably the most popular simplex strainer types on the market, basket and Y-strainers have their distinct advantages and disadvantages. Both have an edge over other inline filter strainers for various application types. However, each has certain qualities to keep in mind when choosing between these pipeline ancillaries.
In this blog, BM Engineering Supplies discusses the similarities and differences between basket strainers and Y-strainers, as well as providing valuable insights to help you make an informed decision if you’re in the market for inline filter strainers.
Basket strainers are synonymous with the term “simplex strainer,” despite other strainer types belonging to this family. Much like Y-strainers, their name derives from their shape. Because of how the basket element seals within the chamber as well as the location of the drain port itself, these inline filter strainers favour a horizontal installation.
When high flow capacities are required, basket strainers are serviced by removing the cover. Doing this will provide access to the basket, which can then be removed, cleaned, and replaced as required.

How do Y-strainers work? Y-strainers are filtration devices that are used in pipelines to remove solid particles from fluids. They have a Y-shaped design with a straining element that captures debris and prevents it from entering downstream equipment. It is due to this that Y-strainers come in various sizes, materials, and end connections, and they are used in many industries to protect equipment and maintain fluid integrity.
Basket strainers are also available in duplex styles as well as the standard singlex variants. Duplex basket strainers do not require shut-off when they become clogged or need to be cleaned. This means that they can be serviced without interrupting the flow of process fluids. As such, a duplex basket strainer would be preferred for continuous flow applications wherever businesses require systems to run without any downtime.
All of the simplex and duplex basket strainers available from BM Engineering Supplies are expertly crafted from cast iron by respected manufacturers, Leengate Valves.
There are many benefits to discuss, but some of the key benefits of using cast iron basket strainers from Leengate Valves are:
There are some notable factors that might lead your business to purchase a stainless steel Y-strainer instead of a basket type. For example, while basket strainers can only be installed horizontally, Y-strainers offer more flexible installation options, with the ability to be installed either horizontally or vertically, making them much more versatile.
Even when manufactured from stainless steel, Y-strainers are a much more cost-effective inline filter strainer option than basket strainers. They also offer a more compact straining solution, which makes them ideal for applications limited by space. Most Y-strainers can also provide higher operating pressure ranges than basket-style strainers, despite their higher flow capacities.
BM Engineering Supplies can provide your business with stainless steel Y-strainers from hygienic specialist manufacturers, INOXPA.
INOXPA stainless steel Y-strainers are ideally suited for pipeline systems or process industry applications with strict sanitary requirements, such as those found in the food and beverage or pharmaceutical industries.
Here are some of the key benefits of using these stainless steel Y-strainers:
As with most pipeline ancillary equipment, the question of which is better will ultimately depend on your application and its characteristics. For example, any pipeline system with flow rates over 150 GPM would stand to benefit from basket strainers due to pressure drop considerations.
If your process media is easily contaminated, you may also be better off with a basket strainer, as these will last longer between cleanings due to their capacity to hold more dirt before they require servicing. On the other hand, if your process media is environmentally safe, meaning your application will only need cleaning infrequently, then a Y-strainer may be less expensive.
For any applications that will operate continuously and are unable to be shut down, duplex basket strainers are the only viable option. Installations will also play a factor in deciding which strainer is best for you, as basket strainers can only be installed horizontally, unlike Y-strainers which can be installed in both directions.
Open area ratios should also be a consideration, as basket strainers have significantly higher ratings than Y-strainers, thus making them better-suited for applications with continuous particle loads.
In summary, the higher open ratio areas and improved holding capacities of basket strainers make them the go-to choice for most liquid filtration applications. Especially those with batch processes or those that require occasional interruptions to the flow. Y-strainers, on the other hand, are better equipped for inert gases or liquid applications that require very low particle loading.
There is no clear answer as to which strainer is better, as they each serve important purposes in their own way. But we hope you have learned all about the differences between basket strainers and Y-strainers.
