Dayco 123453 NPTF Male Hydraulic Adapter Fitting

The Dayco 123453 is an NPTF (National Pipe Taper Fuel) male hydraulic adapter fitting designed for use in high-pressure fluid power and hydraulic systems. NPTF, also known as Dryseal pipe thread, creates a pressure-tight seal through thread interference alone — no sealant or tape is required under normal conditions, making it a reliable choice for demanding hydraulic and pneumatic applications.

Dayco is a globally recognized manufacturer of fluid power components, and this fitting is engineered to meet strict dimensional and performance standards. The tapered thread design ensures a leak-free metal-to-metal seal when properly torqued, making it suitable for use in hydraulic circuits, power steering systems, industrial machinery, and mobile equipment.

Key Features:

• NPTF (Dryseal) male thread configuration for leak-free connections
• Tapered thread design creates a metal-to-metal pressure seal without thread sealant
• Engineered for use in high-pressure hydraulic and fluid power systems
