CUSTOM ITEM: Valve Tool, wrench with 5/16 inch Flat and 1/4 inch opened slit end. ARE-Applied Research brand. 1 EA.
Additional Info:
The 46090‑V1 Valve Tool is a specialized dual‑end wrench designed for safe, precise adjustment of HPLC valve fittings, particularly on Rheodyne™ and Valco™ injector systems. Its unique design allows technicians to tighten or loosen fittings while tubing remains connected, eliminating the need for disassembly.
The 1/4" open‑slit end is engineered to fit over installed tubing and engage 1/4" connecting nuts, enabling adjustments without removing connections. This helps maintain system integrity and avoids introducing leaks or contamination during maintenance.
A key advantage of this tool is its ability to apply torque without twisting or stressing the tubing, preventing common issues such as:
Kinked or deformed tubing
Flow restrictions and pressure instability
Damaged sealing surfaces or leaks
The opposite end features a 5/16" flat wrench, providing additional versatility for common fittings used in HPLC systems.
Its compact design allows easy access in tight, hard‑to‑reach instrument areas, making it an essential tool for routine service and troubleshooting.
Why Use a Valve Tool for HPLC Systems?
Standard wrenches are not designed for chromatography applications and can:
Require tubing removal to access fittings
Cause twisting or torque damage to tubing
Be difficult to use in confined instrument spaces
The Valve Tool Wrench provides:
Safe, in‑place fitting adjustment
Controlled torque application
Improved access in tight areas
