Solid Brass 3-Port Air Compressor Check Valve G1/8″ x G3/8″ x G1/2″ Male Threaded Tube Connector Non-Return Valve

Description

Product Overview

The Uenede solid brass 3‑port check valve is engineered for durability and reliable performance in demanding pneumatic systems. Constructed from high‑grade forged brass, the valve offers excellent resistance to corrosion, wear, and temperature fluctuations, making it suitable for continuous operation in industrial environments. The three male threaded ports—G1/8, G3/8, and G1/2—provide versatile connection options for a wide range of compressors, air tanks, and pneumatic tools. Each thread is precision‑machined to ensure a tight seal, eliminating leaks and maintaining system pressure. The non‑return design automatically blocks reverse airflow, protecting compressors from back‑pressure damage and extending the life of downstream components. With a compact footprint of just over three inches in length, the valve integrates seamlessly into tight spaces while delivering robust flow control.

Usage

This check valve is ideal for air compressors used in manufacturing plants, automotive workshops, and DIY hobbyist setups. It excels in applications where maintaining consistent pressure is critical, such as paint spraying, sandblasting, and pneumatic actuation of machinery. The valve’s three‑port configuration allows users to route compressed air to multiple tools or storage tanks while preventing any back‑flow that could compromise system efficiency. Install the valve on the compressor’s discharge line to safeguard the pump head, or place it downstream of a pressure regulator to ensure one‑way flow to downstream equipment. Because the valve is made of solid brass, it can also be employed in environments with exposure to moisture or mild chemicals without risk of degradation.

Why Choose Us

Uenede is a trusted manufacturer known for precision‑engineered pneumatic components. Each check valve undergoes rigorous quality testing, including pressure‑hold and leak‑rate assessments, to guarantee that it meets or exceeds industry standards.

FAQ

Can this valve be used with plastic tubing?

Yes, the male G‑type threads can be connected to compatible plastic fittings, but for optimal durability in high‑pressure applications, brass or metal adapters are recommended.

What is the maximum pressure rating for this valve?

The valve is rated for up to 150 psi (10 bar) continuous pressure, which covers most standard air compressor and pneumatic system requirements.

How do I know if the valve is installed correctly?

After installation, perform a leak test by pressurizing the system and listening for any hissing sounds. A properly seated valve will show no leaks and will prevent air from flowing backward when the compressor is turned off.

Is there a recommended torque setting for the threads?

Apply a moderate hand‑tighten followed by an additional ½ turn using a wrench. Over‑tightening can damage the threads, while under‑tightening may cause leaks.

What warranty does Uenede provide for this product?

The valve comes with a one‑year limited warranty covering material defects. Contact Uenede customer service with the purchase details for warranty claims.
