| Nut & Sleeve | Creates a strong mechanical seal without flaring. | Available in multiple OD sizes for seamless integration with all Pressure Connections compression fittings. | Nuts and sleeves |
Compression Fitting Advantages
Engineered for performance and simplicity, brass compression fittings offer a perfect balance of strength, corrosion resistance, and ease of installation. Whether you’re working with air, water, gas, or hydraulic systems, brass compression fittings provide a reliable seal without soldering, welding, or adhesives. Additional benefits include:- Quick, tool-free assembly and reusability
- Leak-proof, metal-to-metal sealing design
- Forged brass construction ensures corrosion resistance and long service life
- Interchangeable across SAE-standard brands (Pressure Connections, Parker, Eaton)
- Suitable for hydraulic, pneumatic, and instrumentation systems
- Performs reliably across wide pressure and temperature ranges

Compression Fitting Selection Criteria
When selecting the proper compression fitting for your system, consider the following key factors to ensure proper performance and compatibility:- Connection type and size: Verify proper male/female threading and compression port dimensions for tubing or component compatibility.
- Design and configuration: Choose between straight, elbow, tee, or bulkhead fittings based on available space and fluid direction.
- Fitting features: Adjustable or swivel-style fittings make alignment and installation easier in tight spaces.
- Pressure/load rating: Select fittings that meet the required DIN 2353 load class — from light-duty (L) to heavy-duty (S) — depending on system pressure.
Material Compatibility
- Brass: Best for hydraulic and pneumatic systems.
- Stainless steel: Ideal for corrosive or high-strength environments.
- Plastic: Lightweight, cost-effective choice for low-pressure applications.
Compression Fitting FAQs
What are compression fittings used for?
They connect tubing or piping without welding or threading, making them ideal for modular, maintenance-friendly systems.How do compression fittings work?
The ferrule compresses around the tubing as the nut tightens, forming a secure, leak-free metal-to-metal seal that withstands pressure and vibration.Are brass compression fittings suitable for hydraulic systems?
Yes — brass compression fittings are widely used in hydraulic and pneumatic systems for their corrosion resistance, temperature tolerance, and ease of assembly.Why Choose UPC for Your Compression Fitting Needs?
