Stopcocks Tomopal Nylon with Clear PC Lock Ring Pack of 50

Description

Product Overview

Designed for demanding industrial and scientific applications, the Tomopal 3-Way Nylon stopcocks combine precision engineering with durable materials to deliver reliable fluid control. Each unit features a clear polycarbonate (PC) lock rotating ring that provides visual confirmation of a fully engaged connection, reducing the risk of leaks and ensuring consistent performance. Constructed from high‑grade nylon, the body resists chemical corrosion, temperature extremes, and mechanical wear, making it suitable for a wide range of fluids including solvents, gases, and aqueous solutions. The stopcock’s Luer slip interface is compatible with standard ¼‑inch ID tubing, allowing seamless integration into existing piping systems without the need for additional adapters. The package includes 50 individually inspected stopcocks, each stamped with the model number 100-1140-X050 for easy identification and inventory management. With a compact footprint of 8 × 8 × 6 inches and a weight of just one pound per pack, the product is lightweight yet robust, facilitating easy handling during installation and maintenance. Certified by Tomopal Inc., the stopcocks meet industry standards for quality and safety, and they are listed as #18 in the Luer Stopcocks category on Amazon, reflecting strong market acceptance. Additional technical specifications include a pressure rating of up to 150 psi, a temperature operating range from –40 °C to +120 °C, and a chemical compatibility chart that covers over 200 common industrial fluids. The clear lock ring is engineered to maintain its transparency even after prolonged exposure to UV light, ensuring long‑term visual verification. All components are manufactured in a clean‑room environment to prevent particulate contamination, and each batch undergoes a 100% functional test before shipment.

Usage

In laboratory settings, the stopcocks are ideal for gas‑dissolved‑air (DGA) testing kits, where precise metering of 30 ml or 50 ml glass syringes is essential for accurate analysis of transformer oil and other insulating fluids. The clear PC lock ring allows technicians to verify at a glance that the valve is fully closed before sampling, minimizing exposure to hazardous vapors. In industrial environments, the 3‑way design enables quick switching between multiple process lines, such as diverting coolant flow, isolating a section of a pneumatic circuit, or controlling the discharge of cleaning solvents. Because the nylon construction tolerates a broad temperature range from –40 °C to +120 °C, the stopcocks can be deployed in outdoor installations, high‑temperature manufacturing plants, and refrigerated storage systems without degradation. The Luer slip connection simplifies integration with standard tubing kits, reducing setup time and the need for specialized tools. Maintenance crews appreciate the ability to replace individual stopcocks without disassembling the entire system, thanks to the modular design and the clear visual lock indicator. These stopcocks also perform reliably in high‑pressure applications such as hydraulic test rigs, where they can handle rapid pressure fluctuations without binding. In pharmaceutical production lines, the chemically inert nylon body prevents contamination of sensitive formulations, while the transparent lock ring aids in compliance with Good Manufacturing Practice (GMP) documentation requirements. Whether used in research laboratories, power generation facilities, or chemical processing plants, these stopcocks provide reliable, repeatable performance that supports critical operational workflows.
