Common Applications

The TYKN-K1410-V4 is a G1/4 compression-style fitting sized for 14mm outer-diameter rigid tubing in acrylic, PETG, brass, or copper. The V4 generation uses a 4-O-ring seal stack with an embedded inner sleeve and outer compression collar, designed to hold pressure even if the tube is cut slightly short or seats unevenly. A length-stretch compensation feature allows the inner sleeve to take up minor dimensional variation between tube and port. The brass body screws hand-tight into any G1/4 port; the knurled collar then captures the tube against the inner O-rings without tools.
