The Ralston QLQL-HS2N hose is a high-quality brass quick-test and flexible nylon assembly designed for fast, safe and reliable low pressure connections in the field.

Built to handle demanding industrial environments, this hose is ideal for calibration, testing and instrumentation applications across oil & gas, mining, resources, process and industrial sectors.

Featuring Ralston’s proven Quick-Test connection system, the QLQL-HS2N allows technicians to make pressure connections in seconds without the need for thread tape, spanners or additional tools.

This not only saves time during calibration and maintenance work but also helps reduce the risk of leaks and thread damage commonly associated with traditional fittings.

Durable brass fittings and a robust nylon hose construction ensure the QLQL-HS2N is designed to withstand harsh site conditions while maintaining excellent flexibility and long service life.

A wide 1/4" through-hole diameter prevents liquid collection in low pressure pneumatic applications.

The QLQL-HS2N is particularly well suited for use with pressure calibrators, digital test gauges, manometers, hand pumps and other instrumentation equipment.

A wide variety of interchangeable Ralston Quick-Test adapters provide connections for almost any application.
