The Dial 9316 is a 1/4 inches compression nut sold in a convenient 5-pack, designed for use with 1/4 inches outside diameter copper tubing and standard brass compression fittings. This fitting is a common replacement part in evaporative cooler systems, where water distribution lines must maintain a reliable, leak-free connection throughout the cooling season. HVAC technicians, swamp cooler installers, and maintenance professionals rely on compression nuts like the Dial 9316 to secure water supply tubing at distribution headers, float valves, pump inlets, and distribution line connections inside portable and whole-house evaporative coolers. The compression nut works by threading onto a brass compression fitting body, compressing a ferrule against the outer surface of copper tubing to create a watertight mechanical seal without soldering or special tools. This makes field replacement fast and straightforward. The nut is constructed to resist corrosion, which is critical in evaporative cooler environments where constant water exposure can degrade lesser materials over time. Keeping spare compression nuts on hand reduces downtime during peak cooling season when a leaking fitting can reduce pad saturation and overall cooler output. The 5-pack format means technicians have extras available for multi-unit service calls or to stock a service van. Whether you are replacing a cracked or stripped nut on an existing fitting or completing a fresh cooler installation, the Dial 9316 delivers a dependable, tight seal. Compatible with standard 1/4 inches compression fitting systems widely used across evaporative cooler plumbing, this nut is a practical, cost-effective solution for professional cooler service and installation work.
The Dial 9316 compression nut provides a reliable, corrosion-resistant connection for 1/4 inches copper tubing in evaporative cooler plumbing systems. The 5-pack format makes it a practical choice for professional HVAC technicians servicing multiple units.
