These simple low cost breather vents work well in many applications where metal vents were used in the past. They will not corrode, rust or break down while being economical. The threads have a bit of give being plastic and thus seal well. The threads never seize in place and can be screwed in by hand. The vents are perfect for OEM use. Made in black, they look good on industrial machinery and are essentially trouble free once installed.

These breather vents incorporate a solid base of HDPE plastic and a porous disc of polyethylene. The disc has an average pore size of 60-80 microns. They can be used for low pressure applications of 1 to 5 psi delta P.

The breathers can be cleaned with mineral spirits and are not affected by most acids and bases. Corrosion does not occur in most cases.

Some uses are: Tank venting, computer cabinet venting, gear box vents, and vacuum relief or pressure equalization. They can be used on single-acting cylinders or the upper end of hydraulic cylinders. Temperature range is -60° F to +150° F (-51° to 66° C). Sizes are 1/8″ NPT through 1″ NPT.
