08MFS-18MM ISO 6149 STRAIGHT

Ask A Question

Description & Features

Designed for metric-to-face-seal conversions, the 08Mfs-18Mm Iso 6149 Straight is a straight steel hydraulic adapter connecting an M18x1.5 male metric ISO 6149 O-ring port thread to a 13/16-16 male face seal O-ring (SAE J1453) thread. The straight configuration keeps the connection inline, making it well-suited for compact hydraulic assemblies where routing space is limited.

Constructed from steel and sealed with an NBR O-ring, this fitting is built for reliable fluid containment in standard hydraulic service environments. The ISO 6149 end provides a leak-resistant metal-to-O-ring interface at the port, while the face seal end delivers a positive, vibration-resistant seal at the tube connection. California residents should note this product is subject to Proposition 65 requirements.
