Dial 9504 Plastic Tube Adapters 1/4″ Brass Barbed NPT Set of 2

Description

Product Overview

The Dial 9504 Plastic Tube Adapters are engineered to deliver a precise 1/4 inch connection between threaded and barbed components, bridging the gap between rigid pipework and flexible tubing. Crafted from high‑grade brass, each adapter exhibits excellent resistance to corrosion, wear, and temperature fluctuations, ensuring a long service life even in demanding industrial environments. The NPT (National Pipe Thread) male threads provide a tight, leak‑free seal when mated with standard 1/4″ NPT fittings, while the barbed end securely grips tubing made from PVC, polyurethane, or reinforced plastic. The adapters arrive as a set of two, allowing users to complete symmetrical installations or maintain a spare for future projects. With a compact footprint of 4 × 2.5 × 6.5 inches and a lightweight design of just 13.61 g per piece, they are easy to handle, store, and integrate into a wide range of hydraulic and pneumatic systems.

Usage

These adapters excel in a variety of applications where reliable fluid transfer is essential. In hydraulic circuits, they connect high‑pressure steel tubing to brass manifolds, enabling precise control of actuators, cylinders, and valves. In pneumatic setups, the barbed end accommodates flexible air lines, reducing vibration and noise while maintaining consistent airflow. The adapters are also suitable for low‑pressure water distribution, chemical transfer, and laboratory equipment where a secure, non‑leaking joint is required. Installation is straightforward: simply thread the NPT side into a compatible fitting using a wrench, then push the tubing onto the barbed end until it meets the shoulder. The brass construction tolerates occasional adjustments without stripping threads, making them a favorite among maintenance technicians, system integrators, and hobbyist engineers alike.

FAQ

What tubing materials are compatible with the barbed end?

The barbed side is designed to work with common flexible tubing such as PVC, polyurethane, reinforced nylon, and silicone hoses. For the best seal, ensure the tubing’s outer diameter matches the adapter’s barb size and push it fully onto the barb until it meets the shoulder.

Can these adapters be used in high‑pressure hydraulic systems?

Yes. The brass body and NPT threads are rated for typical hydraulic pressures up to 3000 psi, provided the tubing and connected components are also rated for the same pressure range. Always verify the pressure rating of the entire system before installation.

Do the adapters require any additional sealing compounds?

While the NPT threads are designed to create a seal on their own, applying a thin layer of PTFE tape or pipe dope can enhance leak resistance, especially in high‑temperature or high‑vibration applications. The barbed end does not require sealant; the mechanical grip is sufficient.

Is there a warranty or return policy for these adapters?

Dial offers a limited one‑year warranty covering manufacturing defects. If you receive a damaged or defective unit, contact the seller within the warranty period for a replacement or refund, following the standard return procedures outlined on the purchase platform.

How do I determine the correct orientation when installing?

The threaded side should be inserted into the matching NPT fitting, with the threads rotating clockwise for a tight fit. The barbed side faces outward, ready to receive the tubing. Markings on the adapter’s body may indicate the correct orientation, but the design is symmetrical enough that the functional side is obvious.
