The Ralston Instruments QTQT-HOS-1m is a 1m Quick-Test microbore pressure calibration hose.
Solid brass female Quick-Test hose-end connections resist corrosion, tough conditions and everyday wear and tear.
The QTQT-HOS-1m is part of Ralston's Quick-Test system of pressure hoses and adapters, which offers a universal range of direct connections to virtually any device.
Ralston Quick-Test hoses are self-venting and can be safely attached and detached by hand.
Fast, leak-free, high-pressure connections up to 475 bar / 6,900psi are easily achieved without a wrench or thread sealant.
A burst pressure rating of 1,860 bar / 27,000psi ensures safety and reliability in the field.

With a minimum bend radius of just 26mm, Quick-test hoses are tough, highly flexible and engineered to maintain pressure regardless of twists and turns.
A low volume, 3mm inner diameter ensures Ralston's microbore hoses provide efficient, instant pressure and a highly stable connection during vacuum or pressure calibrations.

• A reflective outer cover reduces temperature sensitivity in operations from -40 to +60°C
• A reinforced polyamide inner core prevents twisting and bending from volume changes across the hose
• A small inner diameter is ideal for transmitting high pressure while consuming very little gas or fluid
