Apache Brass 1/2 in. D Breather Vent is a compact, rugged vacuum-relief solution engineered for sealed systems. Featuring a 1/2" male pipe thread (MPT) inlet and solid brass construction, this vent stands up to harsh industrial environments where oil, humidity, and heat are part of the job. It actively relieves vacuum and balances internal pressure in gear boxes, oil tanks, and reservoirs, helping protect seals, fittings, and internal components from pressure imbalances.

Why this breather vent stands out
Unlike generic vents, the Apache brass vent is purpose-built for reliability in demanding applications. Brass offers excellent corrosion resistance and durability in oily, humid, or temperature-variant environments. The 1/2" inlet matches common on-engine and industrial port sizes, enabling straightforward installation on equipment without adapters. With a proven vacuum-relief function, it helps prevent suction-induced seal damage and uneven pressure that can lead to leaks or equipment downtime.
Ideal use cases
- Gearboxes and gear housings that cycle between hot operation and cold shutdown, where pressure swings occur
- Oil tanks and hydraulic reservoirs needing controlled venting to maintain fluid integrity
- Industrial machinery enclosures and storage reservoirs where air exchange is essential to prevent vacuum buildup
Simple installation tips
- Thread onto compatible ports with a 1/2" MPT connection using appropriate thread sealant for brass
- Ensure the vent opening is clear of debris and not facing potential splash zones to maintain vent performance
- Follow equipment manufacturer guidelines for mounting orientation and clearance
What you get
One Apache Brass 1/2 in. D Breather Vent packaged in a clamshell for durable protection during shipping and handling. Ready to install on compatible gear, tanks, or reservoirs that require reliable vacuum relief and pressure balance.
