Product Description
The NU-VU 31-0457 is a rigid male elbow fitting designed to connect a 1/4-inch OD tube to a 1/8-inch NPT threaded port. This type of compression-style elbow is used to route tubing at a 90-degree angle within commercial appliance plumbing circuits, gas lines, or refrigerant-adjacent pneumatic lines. It provides a leak-resistant transition between a flared or compression tube connection and a standard NPT threaded fitting on a valve, manifold, or component body. Licensed HVAC technicians and commercial appliance service pros install this fitting during system assembly or replacement service on NU-VU commercial equipment.
This elbow fitting is suited for use in commercial food service and appliance environments where tight routing of small-diameter tubing is required. It is a genuine NU-VU parts and accessories item, intended for service and replacement applications on NU-VU commercial appliance systems. The 1/4-inch tube by 1/8-inch NPT configuration is a common interface in gas, pneumatic, or fluid control plumbing found in commercial kitchen and food service equipment.

Always shut off gas supply or depressurize the relevant line before removing or installing any fitting. Do not overtighten NPT threads; use PTFE tape or an approved thread sealant on the NPT connection per manufacturer and applicable code guidelines.
