16MFS-33MM ISO 6149 STRAIGHT

Ask A Question

Description & Features

Designed for metric-to-face-seal conversions in steel hydraulic assemblies, the 16MFS-33MM ISO 6149 Straight fitting connects a 1-7/16-12 male face seal O-ring thread (SAE J1453) on one end to an M33x2.0 male metric ISO 6149 O-ring port thread on the other. The straight configuration keeps connections in-line, making it a practical choice where space and alignment constraints favor a direct coupling between mismatched thread standards.

Constructed from straight steel with an NBR O-ring seal, this fitting is suited for hydraulic systems where reliable sealing between SAE and ISO metric ports is required. The NBR seal material offers compatibility with a broad range of hydraulic fluids commonly used in industrial and mobile equipment applications. California residents should note this product carries a Proposition 65 warning.

So, this here adapter goes from a SAE to a metric thread, right? Just makin' sure I'm readin' that correctly.

You got it. This fitting adapts from a 1-7/16-12 male face seal O-ring thread (SAE J1453) to an M33x2.0 male metric ISO 6149 O-ring port thread.
