Part Number: 4604

Beaded Hose Barb x ORB Male Adapter

Product Overview

The Delphi Fittings Part 4604 is a straight adapter engineered to connect a low-pressure hose to a female SAE O-Ring Boss (ORB) port. This fitting features a beaded hose barb on one end, designed to provide a secure grip for a hose secured with an external clamp. The raised bead offers a positive stop and an excellent shoulder for the clamp to tighten against, preventing hose slippage. The other end features a male SAE O-Ring Boss (ORB) thread, which uses an O-ring to create a superior, leak-free seal in the port. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the 4604 adapter is a durable choice for a wide range of low-pressure fluid transfer systems requiring a high-integrity port connection.

Key Features & Specifications

Material	High-Grade Carbon Steel
End 1 Configuration	Beaded Hose Barb
End 2 Configuration	Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1)
Body Style	Straight Adapter with hex features for wrench tightening.
Sealing Mechanism	Hose Barb End: The hose is pushed over the barbs, and a hose clamp is tightened behind the bead for secure retention. ORB Male End: Utilizes an elastomeric O-ring (seated in the groove on the male ORB fitting) which seals against the chamfered boss of the mating female ORB port.

Crucial Application Note: This fitting is intended for **low-pressure applications only**. While the ORB end provides a high-pressure seal, the hose barb connection is the limiting factor. The overall pressure rating is limited by the hose and clamp type and is not suitable for medium or high-pressure hydraulic systems.

Commonly Available Sizes (Part #4604 Series)

Delphi Fittings offers the 4604 Beaded Hose Barb x ORB Male Adapter in a variety of common sizes. Sizing is typically denoted by the hose inner diameter (ID) for the barb end and the SAE ORB dash size for the threaded end.

Applications

The Part 4604 Beaded Hose Barb adapter is ideal for a wide range of low-pressure applications, including:

Connecting low-pressure oil return lines, engine coolant lines, or air lines to components with high-quality SAE ORB ports.
Automotive systems where a secure, leak-free port connection is desired, but the hose side of the circuit is low-pressure.
Industrial applications including pneumatic lines, general fluid transfer, and drainage systems that require a straight connection to an ORB port.
General purpose plumbing and machinery where a secure, clamped hose connection is needed.

Installation & Usage Guidelines

For the ORB end, ensure the O-ring is correctly sized, lubricated, and seated in its groove. Thread the male ORB end into the female ORB port by hand, and then tighten to the recommended torque for the ORB size using a wrench on the fitting's hex.

Why Choose Delphi Fittings Part 4604?

Secure Hose Connection: The beaded barb provides enhanced retention for a clamped hose compared to a standard barb, preventing slippage in low-pressure applications.
High-Integrity Port Seal: The SAE O-Ring Boss (ORB) end provides a superior, leak-free seal compared to tapered threads.
