Valve Tool, wrench with 5/16 inch Flat and 1/4 inch opened slit end. ARE-Applied Research brand. 5/PK.
Additional Info:
The 46090‑V1‑005 Valve Tool Wrench (5‑Pack) provides a multi‑user, lab‑ready solution for safely adjusting HPLC valve fittings, particularly on Rheodyne™ and Valco™ injector systems. Each tool features a dual‑end design that enables technicians to tighten or loosen fittings while tubing remains connected, significantly improving maintenance efficiency and reducing system downtime.
The 1/4" open‑slit end is specifically engineered to fit over installed tubing and engage 1/4" connecting nuts, allowing adjustments to be made without disconnecting tubing. This is critical for maintaining system integrity, avoiding leaks, and preventing contamination during service operations.
A key benefit of this design is the ability to apply torque without twisting the tubing, helping to avoid:
Kinking or permanent deformation
Flow restrictions and pressure instability
Damage to sealing surfaces and fittings
The opposite end features a 5/16" flat wrench, providing added versatility for common chromatography fittings and components.
The 5‑pack configuration is ideal for laboratories with multiple instruments or technicians, ensuring consistent tool availability across workflows.
Why Choose a 5‑Pack Valve Tool Set?
This configuration is ideal for:
Multi‑instrument HPLC laboratories
Shared service or maintenance teams
Reducing delays caused by limited tool availability
Standardizing maintenance tools across the lab
Provides improved efficiency and readiness for routine service and troubleshooting.
Why Use a Valve Tool for HPLC Systems?
Standard wrenches are not designed for HPLC fittings and can:
Require tubing removal before adjustment
Cause twisting or stress on tubing connections
Be difficult to use in confined instrument spaces
The Valve Tool Wrench is designed to:
Work directly on installed tubing connections
Apply controlled torque without damaging components
Improve access to tight areas around injectors and valves
