Pneu-Draulics Inc. supplies sealing components for aerospace and defense applications, supporting OEMs, MRO providers, and procurement teams with sourcing, engineering support, and fulfillment.
These applications require seals that perform under pressure, withstand temperature variations, and resist exposure to hydraulic fluids and aviation fuels. The team supports material selection, compliance requirements, and ongoing supply for aerospace programs.
Aerospace Seal Distribution and Material Selection Support
Pneu-Draulics operates as an authorized distributor for Parker Hannifin Seal Groups and Hallite, supplying aerospace sealing components to OEMs and MRO providers. Material selection is based on application requirements, including pressure, temperature, and fluid compatibility.
The team supports material selection for aerospace hydraulic seals and fluid power systems, helping match elastomers to operating conditions such as fuel exposure, temperature variation, and system pressure.
Aerospace Seal Sourcing for Defense Contractors
Defense contractors require reliable sourcing processes to maintain production schedules. Pneu-Draulics supports procurement through its CAGE Code 8V217 designation and ISO 9001:2015 quality system.
The company supplies Parker Hannifin DFARS-compliant seals and supports ITAR-regulated applications by maintaining controlled handling of technical requirements and documentation.
Value-Added Services for Aerospace MRO and OEM Operations
Managing individual O-rings and gaskets complicates inventory control for busy MRO facilities. We execute custom kitting programs to consolidate your sealing components into single, ready-to-use packages. This is especially important for aerospace MRO operations managing high volumes of replacement seals and components.
- Custom kitting: Consolidates aerospace sealing components into ready-to-use packages for maintenance and overhaul
- Protective packaging: Prevents UV exposure and moisture damage during storage and transport
- Barcoding and labeling: Supports faster receiving and inventory tracking in MRO environments
- Product engineering: Recreates obsolete or difficult-to-source aerospace sealing components
Sealing Performance in Aerospace Applications
Aerospace sealing components must meet specific performance requirements depending on the application, including exposure to fuels, hydraulic fluids, and temperature extremes. These standards define performance expectations, but material and design selection ultimately depend on the specific aerospace application.
Military and aerospace assemblies demand components built to exact dimensional and material tolerances. We supply NAS1611 aerospace O-rings designed specifically for straight thread tube fittings. Our inventory includes robust MS28775 military seals for standard aviation hydraulic applications. When mechanical operations involve extreme temperatures and jet fuels, we distribute MIL-DTL-25988 fluorosilicone components. This specific material maintains its mechanical stability in harsh environments where standard elastomers break down or lose elasticity.
Material Selection for Aerospace Sealing Applications
Material selection depends on the operating environment, including temperature range, chemical exposure, and system pressure. Selecting the correct elastomer helps prevent seal degradation, leakage, and premature component failure. These materials are commonly used in aerospace sealing solutions for hydraulic and fuel system applications.
- AMS 7276 FKM seals. We supply these fluorocarbon components for high-temperature turbine engine applications requiring aggressive chemical resistance
- AMS-P-83461 nitrile O-rings. We distribute these parts for standard aviation hydraulic systems requiring excellent tear resistance and fluid compatibility
