Contractors, kitchen fitters, and home improvers installing extractor fans or mechanical ventilation systems need a PVC Y piece duct fitting that seats firmly, seals cleanly, and holds its shape over years of continuous airflow.\u003c\/p\u003e\n    \u003cp\u003eThese Y piece ducting connectors are moulded from rigid PVC, offering a smooth internal bore that minimises airflow resistance. Each unit provides a three-way split in a Y configuration, compatible with round duct pipe in inner diameters of 50mm (~2 in), 75mm (~3 in), and 110mm (~4.3 in). Wall thickness is typically 1.5–2.5mm depending on diameter. Sold individually (1 Pcs per order).\u003c\/p\u003e\n    \u003cp\u003eTypical applications include branching a single extractor fan duct to serve two rooms, splitting a bathroom ventilation run to a secondary outlet, and connecting inline duct fans to multi-point extraction systems — all common scenarios where a Y piece vent pipe fitting for extractor fans is the most space-efficient solution.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚠️\u003c\/span\u003e\n    Compatible with standard round PVC duct pipe in 50mm, 75mm, and 110mm inner diameters.
