STAUFF Desiccant Breathers provide advanced protection for hydraulic reservoirs by preventing moisture and particulate contamination. Using a high-efficient desiccant media, these breathers actively absorb water vapor before it can enter the system, helping to prevent corrosion, excessive wear and tear, and even system failure.

Built with durability and ease of maintenance in mind, STAUFF Desiccant Breathers feature rugged housings supported by internal stainless‑steel structures, refillable desiccant media, and replaceable breather elements. A visual color indicator clearly signals when the drying agent is saturated, simplifying maintenance and helping operators stay proactive with system care. Available in multiple sizes and configurations, with optional features such as integrated check valves and compatible refill and maintenance kits, STAUFF Desiccant Breathers deliver a reliable, long‑term solution for keeping critical hydraulic and lubrication systems clean, dry, and protected.

STAUFF Plastic Filter Breather Type SPBN

The Plastic Filter Breather is of a compact design that is available in a threaded or bayonet version. It is designed to be used as filter ports for hydraulic reservoirs. It allows the reservoir to breathe while protecting it from contamination found in harsh environments. This breather is ideal for applications in which space is limited. 

STAUFF Metal Filter Breather Type SMBB

The Metal Filter Breather is available in the bayonet version. It is designed to be used as filler ports for hydraulic reservoirs, allowing the reservoir to breathe while protecting it from contamination found in harsh environments.

STAUFF Level Gauge – Type SNK

The STAUFF SNK series provides both visual and electric fluid level indication, making it a versatile solution for hydraulic reservoirs requiring active monitoring. Designed for systems with maximum tank pressures up to 29 PSI, the SNK gauge incorporates a magnetic float that triggers an electrical switch when the fluid level drops within 2.36 inches of the lower banjo bolt, offering an added layer of protection for equipment. For applications requiring unique dimensions, the SNK series can be manufactured in special lengths up to 37.4 inches, allowing seamless integration into a wide range of reservoir sizes and configurations.

STAUFF Level Gauge – Type SNA

The STAUFF SNA series delivers reliable visual-only fluid level indication for hydraulic reservoirs with maximum tank pressures not exceeding 29 PSI. Engineered for flexibility, the SNA line is ideal for custom applications, offering tailored solutions for various reservoir capacities and dimensions. You can specify custom colors, logos, or markings, enhancing integration with branded equipment or system aesthetics. Like the SNK series, the SNA gauges are also available in custom lengths up to 37.4 inches, ensuring a perfect fit across diverse hydraulic tank designs.

STAUFF Suction Strainers Type SUS serve as the primary filtration stage in hydraulic systems, protecting pumps by capturing coarse contaminants directly at the reservoir intake. Designed for in‑tank installation, they connect to suction lines and must be positioned below the minimum fluid level to maintain consistent flow. Each strainer features a galvanized steel lower end cap paired with either a polyamide or aluminum upper end cap, making them suitable for both mobile and stationary hydraulic applications.

The Type SUS utilizes a durable stainless‑steel wire mesh element (125 μm) as standard, with alternative filtration grades available to meet specific system requirements. This robust construction ensures reliable suction‑side filtration, reduces the risk of cavitation, and enhances overall pump service life by preventing contaminants from entering the hydraulic circuit at its most critical point.
