Plastic Barbed Bulkhead Fitting with Male Thread — Secure Hose-Through-Panel Connection

When you need to route flexible tubing through a tank wall, panel, or enclosure without leaks, a loose or mismatched fitting quickly becomes a frustrating problem. These plastic barbed bulkhead fittings are designed for hobbyists, DIYers, aquarium builders, irrigation installers, and lab technicians who need a reliable, thread-sealed pass-through connection in a compact plastic body.

Each fitting consists of a barbed hose tail on one or both ends and a male-threaded shank that passes through a drilled panel hole, secured from the other side with the included nut. Available in metric thread sizes from M5 to M16 and BSP/G imperial sizes from G1/8 to G3/4, with barb diameters ranging from 1.6mm (≈1/16") to 20mm (≈25/32"). Half-way (single-barb) variants are also available for one-sided hose connections. Sold in quantities of 1, 5, or 10 pieces per order.

Typical use cases include aquarium sump and refugium plumbing, drip irrigation manifold pass-throughs, hydroponics reservoir fittings, and fluid transfer setups in laboratory or industrial enclosures where a barbed bulkhead hose connector with male thread is needed.

🔗 Thread Compatibility: Available in metric (M5–M16) and BSP/G imperial (G1/8, G1/4, G3/8, G1/2, G3/4) threads. Select the Dia(mm) variant that matches your panel port thread and hose inner diameter. Each set includes the bulkhead nut.
⚠️ Size Confirmation: Variant labels follow the format Barb Dia – Thread Size – Barb Dia (e.g., 1.6-M5-1.6 means 1.6mm barb, M5 thread, 1.6mm barb). Please verify your hose ID and panel port thread before ordering. Contact us if you need help confirming fit.

✅ Key Features of These Plastic Barbed Bulkhead Fittings

  • 🔩Dual Thread Standard Coverage — Available in both metric (M5–M16) and BSP/G imperial (G1/8–G3/4) threads, covering the most common panel port sizes used in aquariums, irrigation, and fluid systems.
  • 🪝Barbed Hose Grip Design — The ribbed barb profile grips flexible tubing securely without clamps in low-pressure applications, reducing the chance of hose pull-out during normal operation.
  • 🔧Nut Included for Panel Mounting — Every variant ships with the matching bulkhead nut, so you can install the fitting through a drilled hole and tighten from the back side without sourcing additional hardware.
  • 📐Wide Size Range in One Listing — Barb diameters from 1.6mm (≈1/16") to 20mm (≈25/32") let you match the fitting to your exact hose inner diameter, minimizing the need to shop across multiple listings.
  • 💧Plastic Body for Corrosion Resistance — The plastic construction resists rust and mild chemical exposure, making these fittings well-suited for aquatic, irrigation, and light fluid-handling environments.
  • 📦Flexible Quantity Options — Order 1, 5, or 10 pieces per variant to match your project scale, whether you need a single replacement fitting or a batch for a larger plumbing installation.

❓ Frequently Asked Questions

How do I choose the right size barbed bulkhead fitting?

Match the barb diameter to your hose inner diameter (ID) and the thread size to your panel or tank port. The variant label format is Barb Dia – Thread Size – Barb Dia (e.g., 1.6-M5-1.6 means a 1.6mm barb, M5 thread shank, and 1.6mm barb on the other side). For inch equivalents: 1.6mm ≈ 1/16", 3.2mm ≈ 1/8", 6.4mm ≈ 1/4", 9.5mm ≈ 3/8", 12.7mm ≈ 1/2". When in doubt, measure your hose ID and panel hole thread before ordering.

What thread standards are available — metric or imperial?

Both. Metric options include M5, M6, M8, M10, M12, M14, and M16. Imperial BSP/G options include G1/8, G1/4, G3/8, G1/2, and G3/4. Select the thread that matches your tank, manifold, or panel port. If you are unsure whether your port is metric or BSP, a thread gauge or caliper measurement of the port diameter and pitch will help confirm.

What is the pressure or load capacity of these fittings?

These plastic barbed bulkhead fittings are generally intended for low-to-medium pressure fluid transfer — typically aquariums, drip irrigation, and laboratory tubing setups. They are not rated for high-pressure hydraulic systems. Specific pressure ratings depend on the resin grade and installation conditions. Contact us to confirm suitability for your application.

Can these fittings be used outdoors or with corrosive fluids?

Plastic fittings are generally resistant to moisture and mild chemicals, making them suitable for outdoor irrigation and aquatic environments in most cases. They are typically not recommended for strong solvents, concentrated acids, or prolonged direct UV exposure without additional protection. Contact us to confirm compatibility with your specific fluid or environment before ordering.

What hose types work with these barbed fittings?

These barbed fittings are typically compatible with flexible PVC tubing, silicone hose, polyurethane tubing, and similar soft-walled hoses. The barb diameter should match or be very slightly larger than the hose inner diameter for a secure, leak-resistant grip. For higher-pressure applications, a hose clamp over the barb is generally recommended.

Does each fitting come with a nut?

Yes. All variants in this listing are labeled "with nut," meaning each fitting includes the corresponding bulkhead nut for panel or tank wall installation. No additional hardware is needed to mount the fitting through a drilled hole.

How many pieces are included, and is bulk pricing available?

You can choose from 1 pc, 5 pcs, or 10 pcs per order using the QTY(pcs) option at checkout. Larger quantities offer a lower per-unit cost. If you need quantities beyond 10 pieces or have a wholesale inquiry, please contact us directly.
