SKU CH-7H89-K2SGX

A breather cap vents hydraulic reservoirs while filtering particles down to 40 microns

  • Provides free airflow into hydraulic reservoirs
  • Oil-resistant filter traps particles down to 40 microns
  • Fits 1/2 NPT threaded ports on tanks
  • Built for hydraulic fluid, oil and coolant systems
  • New breather cap from Buyers Products

Hydraulic Tank Breather Cap

The Buyers HBF8 vent plug fits hydraulic tanks and reservoirs that need a free flow of clean air. Oil-resistant filter elements block dirt and dust particles as small as 40 microns. It threads into a 1/2 NPT port and suits fluid, oil, chemical and coolant systems. The cap helps maintain reservoir pressure balance during operation.

1/2 NPT Threaded Mount

Brass construction with a 1-15/32 inch overall height provides a secure seal in standard hydraulic ports. The filter media resists oil degradation while allowing continuous air exchange. No moving parts mean there is nothing to wear out or adjust after installation. The compact profile fits tight machinery envelopes without interfering with nearby components.

Check Port Size and Clearance

Verify that your reservoir has a female 1/2 NPT opening before ordering. Confirm the 1-15/32 inch installed height clears surrounding brackets, hoses or guards. Ensure the 40 micron filtration rating meets your system cleanliness requirements. This breather is not suited for pressurised vessels that exceed atmospheric venting needs.

Questions about this item

What does the 1/2 NPT thread size limit in practice?

The 1/2 NPT thread fits standard hydraulic tank ports and caps airflow at the filter's 40 micron rating.

What clearance does the 1-15/32 inch height need to fit?

The 1-15/32 inch overall height requires that much vertical space above the reservoir port for the filter element to sit clear.

How is the vent plug installed and what step is often missed?

Thread the 1/2 NPT base into the reservoir port by hand then snug with a wrench; the step often missed is checking the filter element seats flat so air flows through the 40 micron media.
