Swagelok SS-QF4-S-400 is a high-performance 316 stainless steel quick-connect stem designed for the QF4 series. This component provides a full-flow path without an internal valve, ensuring unrestricted flow and minimal pressure drop in critical transfer, drain, and vent systems. It features a 1/4 in. Swagelok tube fitting end connection and is equipped with Fluorocarbon FKM O-rings, providing a robust seal for a wide range of industrial applications.

System Performance

Designed for ease of maintenance and reliability, the QF4 series quick-connects allow for rapid coupling and uncoupling. When coupled with a compatible body, this stem achieves a maximum flow coefficient (Cv) of 2.2. The assembly is rated for a working pressure of up to 6000 PSIG (413 BAR) at room temperature and maintains integrity up to 100 PSIG (6.8 BAR) at temperatures as high as 400°F (204°C).

Maintenance and Usage

Swagelok full-flow quick-connects are ideal for systems where unrestricted flow is the priority. The valve-less stem design simplifies the flow path and reduces potential points for media entrapment, making it suitable for quick maintenance and system flushing.

Product Selection

When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user. Do not mix or interchange Swagelok products or components with those of other manufacturers.
