Ask A Question

Description & Features

Constructed from stainless steel, the 04MP-04FP Straight Expander Stnls is a straight-configuration pipe thread adapter designed for hydraulic and industrial fluid systems requiring corrosion-resistant connections. Both ends feature 1/4-18 NPTF threads conforming to SAE J476, a male NPTF on one end and a female NPTF on the other, making it suitable for inline connections where thread type or flow direction needs to be maintained in a straight run.

Rated to 6,000 PSI maximum dynamic pressure, this fitting handles demanding hydraulic service conditions. The stainless steel construction offers durability in environments where moisture, chemicals, or temperature cycling would degrade carbon steel alternatives. Part of Brennan Industries' Series 5405, it carries a California Prop 65 designation as noted by the manufacturer.

So, this is stainless steel, right? I need something that won't rust up on me quick.

That's correct. The 04MP-04FP Straight Expander is constructed from stainless steel, making it a good choice for hydraulic systems exposed to moisture or harsh chemicals where standard carbon steel would corrode.
