Brass In-Line Y Strainer Compression 15mm 22mm — Stainless Steel Mesh Heating Cold Water Filter

Brass In-Line Y Strainer Compression 15mm 22mm — Stainless Steel Mesh Heating Cold Water Filter

The Brass In-Line Y Strainer is a compact compression-fit Y-pattern strainer for 15mm or 22mm copper pipework, providing debris filtration on heating systems, cold water supplies, and boiler filling loops. The Y-shaped body positions the stainless steel mesh filter element at an angle to the flow, giving a large effective filter area in a short overall body length. The mesh can be removed and cleaned without disconnecting the strainer from the pipework — remove the end plug, withdraw the mesh basket, rinse and refit. Solid brass construction with a stainless steel mesh insert offers long service life in both heating (closed system) and cold water (open/mains) applications. Available as 15mm (for domestic hot and cold supply lines, zone valve inlets, boiler filling connections) and 22mm (for main heating flow and return, pump inlets, manifold connections).

⚡ 15mm vs 22mm — When to use each
15mm: Domestic cold water supplies, filling loops, zone valve inlets, condensate connections, boiler mains cold feed, individual appliance supplies where debris protection is needed before a sensitive valve or component.
22mm: Main heating flow and return pipework, pump inlets, manifold feeds, larger cold water mains, any 22mm supply serving multiple outlets where a single strainer protects downstream components.
Features & Benefits
✔ Serviceable Without Removal
The Y-pattern design puts the mesh element in the angled leg of the Y — the end plug unscrews and the mesh basket slides out for cleaning without removing the strainer body from the pipework. Provided isolation valves are fitted upstream and downstream (or the system is drained), the strainer can be cleaned in situ in minutes. This is a significant maintenance advantage over in-line filter balls that require the full fitting to be replaced when clogged.
✔ Solid Brass Body — Stainless Steel Mesh
The body is solid brass, resistant to corrosion in both heating system water and cold water mains. The stainless steel mesh insert does not corrode or degrade in contact with system fluid, maintaining its filtration integrity over many service intervals. Unlike plastic-bodied strainers, the brass construction withstands the full temperature range of heating applications without degradation or distortion.
✔ Compression Fittings — No Soldering
Standard compression end fittings with included olives mean the strainer can be installed on existing copper pipework without a blowtorch — appropriate for retrofit, as-lived situations, or anywhere open flame is not permitted. Compression fittings also allow the strainer to be removed for replacement without cutting the pipework.
✔ Protects Valves and Components Downstream
Scale particles, flux residue, pipe swarf, and system debris will clog thermostatic valve cartridges, damage pump impellers, and cause zone valves to jam or fail to seal. A strainer fitted before a sensitive component — filling loop, thermostatic mixing valve, zone valve, pump — extends the service life of those components and reduces callout frequency. Particularly valuable on older properties where pipe scale is present.
