Swagelok SS-400-1-4 Stainless Steel Tube Fitting, Male NPT

Description

Product Overview

The Swagelok SS-400-1-4 is a precision‑engineered stainless steel tube fitting designed for high‑performance fluid handling in both hydraulic and pneumatic environments. Constructed from premium 304 stainless steel, the fitting offers exceptional corrosion resistance, temperature tolerance, and mechanical strength, ensuring a reliable seal even under demanding pressure cycles. With a 1/4″ tube outer diameter (OD) and a 1/4″ male NPT (National Pipe Thread) interface, this component provides a straightforward, leak‑free connection that integrates seamlessly with standard tubing and pipework. The compact dimensions—1.57 x 0.79 x 0.79 inches—and lightweight design (1.45 ounces) make it easy to install in tight spaces while maintaining structural integrity. Swagelok’s reputation for quality control guarantees that each fitting meets rigorous industry standards, delivering consistent performance across a wide range of applications.

Usage

Designed for versatility, the SS-400-1-4 fitting is ideal for use in manufacturing plants, process control systems, laboratory equipment, and field‑service installations where precise fluid control is essential. Its stainless steel composition makes it suitable for corrosive media such as chemicals, water treatment solutions, and food‑grade fluids, while the male NPT thread provides a secure, torque‑resistant connection to valves, pumps, and manifolds. Engineers and technicians appreciate the ease of assembly—simply push the tubing into the fitting and tighten the NPT thread to achieve a hermetic seal without the need for additional sealing compounds. This fitting excels in high‑pressure applications up to 10,000 psi, making it a trusted choice for aerospace, automotive, and oil‑and‑gas sectors that demand uncompromising reliability.
