Windscreen Washer Pipe Connector — T-Piece, Y-Piece & Straight Joiner

A cracked or disconnected washer pipe connector is one of the most common causes of windscreen washer failure — and one of the easiest to fix. These plastic pipe connectors join, split, or extend standard windscreen washer tubing in T, Y, and straight configurations, restoring full washer system function without replacing the entire hose assembly.

Technical Specifications

Key Features

• Three configurations: Straight joiner for simple repairs, T-piece for splitting one line into two, Y-piece for angled splits in tight engine bay routing
• Barbed retention: Barbed connector ends grip the inside of the hose tubing — no clamps required for standard washer system pressures
• Fuel and water resistant plastic: Resists degradation from windscreen washer fluid, water, and light hydrocarbon exposure
• Universal sizing: Fits the standard 4–6 mm ID tubing used in the vast majority of OEM windscreen washer systems

Frequently Asked Questions

Q: What hose inner diameter does this connector fit?
A: These connectors are sized for standard windscreen washer tubing with an inner diameter of approximately 4–6 mm. This covers the OEM washer hose size used on most European, Japanese, and American passenger vehicles.

Q: Can I use the T-piece to add a second washer nozzle?
A: Yes. The T-piece connector allows you to split a single washer line into two outputs — useful for adding a bonnet (hood) nozzle, headlight washer, or a second windscreen nozzle.

Q: Is this suitable for fuel line use?
A: These connectors are compatible with light fuel exposure (petrol/gasoline splash), but are not rated for continuous fuel line pressure. For dedicated fuel line applications, use fuel-rated connectors with appropriate pressure ratings.

Q: How do I install the connector without leaks?
A: Cut the hose cleanly with a sharp blade (no ragged edges), push the hose firmly onto the barbed connector end until it seats fully, and check for leaks by running the washer system. No adhesive or clamps are required for standard washer system pressures.
