A2 Stainless Cross 4-Way Barbed Hose Connector — Split Any Line in Four Directions
Routing coolant, fuel, air, or water through a single junction point is a constant challenge in automotive builds, irrigation systems, and pneumatic setups. A loose plastic tee cracks under heat; a corroded fitting contaminates the line. These A2 stainless steel cross 4-way barbed hose connectors are built for DIYers, mechanics, and small-shop operators who need a reliable, rust-resistant solution that holds up across multiple media types.
Each connector is machined from A2 (304) stainless steel and features four equal barbed ports. Available in six sizes — 8mm (5/16"), 10mm (3/8"), 13mm (1/2"), 16mm (5/8"), 20mm (3/4"), and 25mm (1") — to match a wide range of hose inner diameters. Sold in packs of 1, 2, 4, or 5 pieces so you can order exactly what your project requires.
Typical applications include automotive coolant distribution, garden irrigation manifolds, compressed air line splitting, and fuel system branching in small engines. The barbed profile grips the hose interior for a secure push-fit connection, especially when paired with hose clamps.

Compatibility: Fits standard flexible hoses with inner diameters of 8mm, 10mm, 13mm, 16mm, 20mm, or 25mm. Compatible with air, water, fuel, and gas lines — verify chemical compatibility with your specific fluid before installation.
✅ Key Features of These A2 Stainless Cross 4-Way Barbed Hose Connectors
-
🔩
A2 (304) Stainless Steel Construction — Resists rust, oxidation, and mild chemical exposure, making these fittings suitable for outdoor, automotive, and wet environments where carbon steel would corrode.
-
✚
True Cross 4-Way Design — All four ports exit at 90° angles in a single plane, enabling clean multi-branch hose routing without additional tees or adapters — ideal for cross 4-way barbed hose joiner applications.
-
📐
Six Size Options (8–25mm) — Covers the most common hose inner diameters from 8mm (5/16") up to 25mm (1"), so one product listing handles a wide range of barbed hose connector size needs.
-
🔄
Multi-Media Compatibility — Engineered for use with air, fuel, water, and gas lines, reducing the need to stock separate fittings for different fluid systems in your shop or garage.
-
🛠️
Push-Fit Barbed Profile — The stepped barb geometry grips the hose bore on insertion and resists pull-out forces. Secure with a hose clamp for pressurized or vibration-prone installations.
-
📦
Flexible Pack Quantities — Available in 1, 2, 4, or 5-piece packs so you can match your exact project quantity without overstocking — useful for both single repairs and small-batch builds.

❓ Frequently Asked Questions
How do I choose the right size barbed hose connector?
Match the barb size to your hose's inner diameter (ID). For example, an 8mm barb fits a hose with an 8mm (5/16") inner bore; a 25mm barb fits a 25mm (1") ID hose. Always measure the inside of your hose — not the outer wall. When in doubt, size down slightly: a snug barb creates a better seal than a loose one.
What pressure can these cross hose connectors handle?
A2 stainless steel barbed fittings generally handle low-to-medium pressure applications. For best results, secure each barb with a hose clamp. Exact pressure ratings depend on hose material, wall thickness, and clamp torque. Contact us to confirm suitability for high-pressure systems before ordering.
Are these connectors suitable for outdoor or marine use?
Yes. A2 (304) stainless steel offers good corrosion resistance in most outdoor and mildly humid environments. For saltwater or highly corrosive marine applications, A4 (316) stainless is typically recommended. These connectors are well-suited for garden irrigation, automotive engine bays, and general outdoor installations.
What fluids and gases are these connectors compatible with?
These cross connectors are generally compatible with air, water, fuel, and gas lines when used with appropriate hose materials. Always verify chemical compatibility between the stainless steel fitting and the specific fluid or gas in your application — particularly for aggressive solvents or concentrated acids.
Do I need hose clamps with barbed fittings?
For low-pressure air or water lines with a snug-fitting hose, the barb alone may hold adequately. For fuel, gas, or any pressurized application, hose clamps are strongly recommended to ensure a leak-free, pull-resistant connection. Use clamps rated for your operating pressure.
Can I use these connectors to split one hose line into four?
Yes. The cross (4-way) design allows you to connect four hose lines at a single junction — ideal for irrigation manifolds, coolant distribution, pneumatic circuits, and similar multi-branch setups. Flow will divide across all four ports, so factor this into your system's flow-rate calculations.
Are all four ports the same diameter on the cross connector?
Yes, all four barbed ports on each connector share the same nominal diameter (e.g., all 10mm on the 10mm variant). Select the size that matches your hose inner diameter. If you need a cross connector with mixed port sizes, contact us to confirm availability.
How many pieces do I need for a typical irrigation or coolant project?
This depends on the number of branch points in your system. A single cross connector handles one 4-way junction. For a small garden drip system with two split points, a 2-pack is typically sufficient. For larger installations or to keep spares on hand, the 4- or 5-pack offers better value per piece.
