Push-Fit Brass Adapter for Vacuum Lines

The Legris 3175 53 08 is a push-fit adapter fitting designed for vacuum applications. It connects a tube with an outer diameter of 1/8 in to a male NPT thread of 1/16 in. The brass body uses material grade C36000 for corrosion resistance. Supplied in a pack of 10 for multiple connection points.

Rated to 290 psi and 175 Degrees F

Maximum operating pressure reaches 290 psi while the temperature limit sits at 175 Degrees F. The compact overall length of 13/32 in keeps the assembly short in tight routing. Brass construction handles pressure cycles without deformation. No moving parts means silent operation under normal vacuum or pressure use.

Pre-Applied Sealant Speeds Installation

Each fitting includes pre-applied thread sealant on the male NPT side, removing the need for separate tape or paste. The push-to-connect end grabs the 1/8 in tube instantly without tools. Silver finish allows quick visual inspection of thread engagement. Pack of 10 supports batch assembly or spares stock.

Questions about this item

How do I install the 1/8 in push-to-connect side and the 1/16 in MNPT thread without leaks?

Push the 1/8 in tube firmly until it seats on the internal grip ring; thread the 1/16 in MNPT end into the port using the pre-applied sealant — do not add tape or paste, which can prevent the sealant from working.

What maintenance or replacement will the brass body and pre-applied thread sealant need over time?

Inspect the fitting at each system service; replace the unit if the brass shows dezincification, the grip ring loses retention, or the sealant has washed out — typically after several pressure cycles at 290 psi.

Which limit appears first during sustained operation at the 290 psi rating?

The 175 °F temperature ceiling is reached before the 290 psi pressure limit in most continuous-duty applications, so monitor fluid temperature to stay within the brass C36000 rating.
