6AN Male to M14x1.5 O-Ring Aluminum Black

The 6AN Male to M14x1.5 O-Ring Aluminum Black fitting by Redhorse Performance is a precision hydraulic adapter engineered for high-pressure fluid transfer systems in tactical vehicles, weapon platforms, and performance machinery. This adapter bridges 6AN (6/8-inch nominal) male ports to M14x1.5 metric threaded female ports, making it essential for integrators working with mixed SAE and metric hydraulic architectures. Whether you're building custom hydro-assist systems, upgrading mil-spec equipment, or restoring specialized platforms that demand reliable pressure coupling, this fitting delivers the durability and precision that field operations require.

Constructed from lightweight aluminum alloy with a hardened black anodized finish, the 6AN Male to M14x1.5 O-Ring fitting resists corrosion and oxidation in harsh tactical and outdoor environments. The dual o-ring design ensures redundant sealing at the connection interface, critical for maintaining system integrity under sustained pressure cycles. The metric M14x1.5 threading provides a secure, leak-free connection to European and NATO-standard component ports, while the 6AN male end accepts standard braided AN hose or rigid tubing via a 37-degree JIC flare seat, the industry-standard for military and aerospace hydraulic systems. Its compact 2.84 x 1.1 x 4.42-inch envelope and 0.055-pound weight make it ideal for weight-conscious builds where every fraction matters.

Tactical technicians and armorsmiths favor Redhorse Performance fittings for platform upgrades involving mixed component sourcing—common when modernizing legacy mil-spec equipment or integrating contemporary add-ons. Installation requires hand-tight seating plus 1/2 to 1 full turn with appropriate wrenches to secure the o-ring seal without over-torquing the aluminum body. Verify system pressure ratings and fluid compatibility before deployment; this adapter is rated for standard MIL-H-5606 mineral hydraulic fluid and synthetic alternatives within manufacturer specifications. Stock this fitting for rapid-turnaround builds and field repairs where split-second connection reliability is non-negotiable.
