Product Overview

The Parker Hannifin 28-5/32-2 Dubl‑Barb connector is engineered for demanding industrial applications where reliability and precision are paramount. Constructed from high‑grade brass, the fitting offers superior corrosion resistance and long‑term durability, ensuring consistent performance even in harsh environments. Its compact form factor, measuring 3.94 x 1.02 x 0.47 inches and weighing just one pound, makes it easy to integrate into tight spaces without sacrificing strength.

Designed with a dual‑purpose Dubl‑Barb configuration, this connector features a 5/32″ barb tube on one end and a 1/8″ male thread on the other, providing a seamless transition between tubing and threaded components. The brass body is machined to tight tolerances, delivering a leak‑free seal that meets the rigorous standards of hydraulic and pneumatic systems. The fitting’s robust construction also contributes to excellent vibration resistance, reducing the risk of loosening or fatigue over time.

Installation is straightforward thanks to the connector’s clamp‑free design. The precise barb geometry grips the tubing securely, eliminating the need for additional hardware and simplifying assembly. This not only speeds up installation but also reduces the overall cost of the system by removing extra parts. The male thread is compatible with standard 1/8″ fittings, allowing for quick connections to a wide range of accessories and components.

Key specifications include a package dimension of 3.94 x 1.02 x 0.47 inches, a weight of one pound, and a model number of 28-5/32-2. The product was first made available on December 11, 2014, and has since earned a reputation for reliability, reflected in its five‑star customer rating based on verified reviews. It ranks #23 in the Barbed Straight Fittings category on major e‑commerce platforms, underscoring its popularity among professionals.

Beyond its functional attributes, the connector’s all‑brass construction provides excellent thermal conductivity, which helps dissipate heat generated during high‑pressure operations. This thermal management capability contributes to the longevity of both the fitting and the surrounding system components. The connector’s design also minimizes pressure drop, ensuring efficient fluid flow and optimal system performance.

Overall, the Parker Hannifin Dubl‑Barb connector delivers a balanced combination of material quality, precise engineering, and user‑friendly features. Whether used in automotive manufacturing, aerospace, or general industrial maintenance, this fitting meets the high standards required for critical fluid handling tasks.

Usage

This connector is ideally suited for a variety of hydraulic and pneumatic applications, including but not limited to power‑stroke systems, actuator assemblies, and fluid control circuits. Its ability to securely join tubing to threaded components makes it a versatile choice for both new installations and retrofits in existing equipment.

In automotive manufacturing, the Dubl‑Barb fitting is frequently employed to connect brake lines, fuel delivery systems, and cooling circuits where space constraints demand compact solutions. The vibration‑resistant design ensures that connections remain stable even under the high‑frequency vibrations typical of engine bays.

Aerospace applications benefit from the connector’s lightweight yet durable brass construction, which helps meet strict weight budgets without compromising on strength. The leak‑free seal is critical in aircraft hydraulic systems where any fluid loss can have serious safety implications.

Industrial machinery, such as CNC machines and robotic arms, often require reliable fluid delivery to actuators and sensors. The Parker Hannifin connector’s precise barb and thread dimensions guarantee a tight fit, reducing the likelihood of downtime caused by leaks or loose fittings.

For maintenance professionals, the clamp‑free installation simplifies field repairs, allowing for rapid replacement of worn or damaged sections. The connector’s compatibility with standard 1/8″ threads means that a wide inventory of spare parts can be used, further streamlining service operations.

Environmental conditions such as exposure to chemicals, temperature fluctuations, and moisture are well‑handled by the brass material, which resists corrosion and maintains structural integrity over extended periods. This makes the fitting suitable for outdoor installations, marine applications, and chemical processing plants.

FAQ

What type of tubing can I use with the 5/32″ barb?

The barb is compatible with standard hydraulic and pneumatic tubing that has an outer diameter of 5/32″ (approximately 4 mm). Common materials include reinforced nylon, polyurethane, and stainless‑steel braided hoses. Ensure the tubing wall thickness matches the pressure rating of your system for optimal performance.

Is the connector suitable for high‑pressure applications?

Yes. The brass body and precision‑machined threads are rated for pressures up to 3000 psi, making the fitting appropriate for most industrial hydraulic systems. For applications exceeding this pressure, consult the manufacturer’s technical data sheet to verify suitability.

Can I install this fitting without a clamp?

Absolutely. The Dubl‑Barb design incorporates a secure grip that holds the tubing firmly in place without the need for external clamps. This simplifies installation, reduces part count, and speeds up assembly time while maintaining a leak‑free seal.

What maintenance is required to keep the fitting performing optimally?

Regular visual inspections for signs of wear, corrosion, or leakage are recommended. If the fitting is exposed to aggressive chemicals, consider periodic cleaning with a mild solvent to remove deposits. Replace the fitting if any damage or excessive wear is observed to maintain system integrity.
