The JW-Lok 316 Stainless Steel Compression Fitting is engineered for secure, leak-resistant connections between stainless steel tubing and NPT-threaded pipe. The 1/4” tube x 1/4” NPT male connector features a twin ferrule compression design, offering performance in high-pressure, high-vibration, and high-temperature environments. Ideal for use in gas lines, instrumentation, chemical processing, and fluid transfer systems, the coupling allows quick assembly without soldering, threading, or welding. The double ferrule construction enhances seal integrity and is especially effective under vacuum and high-vibration conditions. Crafted from durable 316 stainless steel, this fitting handles temperatures from -325°F to 800°F, and pressures up to 8000 psi. The NPT threads comply with ASME B1.20.1 and SAE AS71051 standards, ensuring compatibility and performance in critical industrial environments. Whether you're building lab systems, hydraulic lines, or compressed gas setups, the precision fitting delivers strength, safety, and efficiency.
