1/2 and 3/4 Boiler Filter Sizes
Common boiler filter connection sizes and use cases for wholesale buyers.
The terms 1/2 and 3/4 refer to nominal inch connection sizes used in heating and plumbing systems. Correct selection should also verify thread direction, body dimensions, strainer fit and the reference product.
1/2 connection filters
The 1/2 connection is commonly used in smaller line connections and relevant spare-part applications. Male/female thread arrangement and overall body dimensions should be confirmed before bulk ordering.
3/4 connection filters
The 3/4 connection is a common option for larger heating and plumbing connections. Overall length, wrench area, chamber dimensions and inner strainer design may differ between models.
Is nominal size alone sufficient?
No. Products with the same nominal connection can still differ in geometry, thread arrangement, internal filter construction and packaging. A sample or dimensioned image reduces the risk of mismatch.
- Connection and thread direction
- Overall body length and diameter
- Inner strainer dimensions
- Carton quantity and packaging format
