Stainless Steel Valve HornBlasters 1/4″ High Flow

Description

Product Overview

The HornBlasters VA-4-SS is a precision‑engineered emission air check valve constructed from premium stainless steel. Designed for a 1/4″ (0.25 inch) inlet, it features a high‑flow 2.5 mm orifice that outperforms standard valves by delivering greater air volume while maintaining back‑pressure control. The weather‑resistant coil protects internal components from moisture, dust, and corrosion, extending service life even in demanding environments. With a National Pipe Tapered (NPT) connection, the valve integrates seamlessly into existing automotive emission systems. It weighs just one pound, making it lightweight yet robust, and comes with a pre‑attached mounting bracket for quick, tool‑free installation.

Usage

This valve is ideal for modern gasoline and diesel engines that require reliable emission control. Install it in the intake manifold, crankcase ventilation, or any location where an air check valve is specified. The stainless‑steel construction tolerates engine bay heat and exposure to road salt, making it perfect for daily commuters, performance vehicles, and fleet trucks. Whether you are performing a routine maintenance service or replacing a failed component, the VA‑4‑SS restores optimal airflow and helps your vehicle meet emissions standards.

FAQ

What vehicles are compatible with this valve?

The VA‑4‑SS fits any vehicle that specifies a 1/4″ (0.25 inch) NPT emission air check valve, including most passenger cars, light trucks, and some diesel applications.

Do I need to purchase additional hardware for installation?

No. The valve ships with a pre‑attached mounting bracket and the necessary NPT threads, so standard wrenches are sufficient for a secure fit.

Is this valve rated for high‑temperature engine bays?

Yes. Stainless steel construction and the weather‑resistant coil are designed to operate reliably in temperatures up to 150 °C (302 °F).

Can this valve be used in a performance tuning setup?

Absolutely. The high‑flow orifice improves airflow, which can benefit tuned engines seeking optimal vacuum stability while maintaining emissions compliance.

What is the warranty coverage?

HornBlasters offers a one‑year limited warranty covering defects in material and workmanship. Replacement is provided free of charge if the valve fails under normal operating conditions.
