Filler, breather & level plugs
Filler, breather, drain and level plugs for reservoirs: small parts with a big impact on reliability and maintenance.
Filler, breather, drain and level: four small functions that decide a reservoir’s life. The breather balances internal pressure as oil level rises and falls with the cylinders; the filtered filler plug keeps top-up dirt out; the drain turns oil changes into a quick job. G 3/8" to G 3/4" threads, PA and steel materials, compatibility across the whole Gazzera reservoir range.
Contamination is the number one cause of hydraulic component failure, and plugs are the first barrier: choosing them well (and replacing a clogged breather) costs a few euros and prevents the most expensive failures. On Gazzera units the correct plugs for reservoir and orientation are already in the BOM.
