Check Check Material Composition

Brass fittings offer superior durability and rust resistance compared to aluminum. Stainless steel is ideal for pneumatic or high-pressure applications. Plastic components are generally best for temporary or light-duty tasks only.

Value Verify Thread Compatibility

Ensure the fittings match your existing equipment thread types. Garden hoses typically use 3/4-inch GHT threads. Air compressors usually require 1/4-inch NPT threads. Using mismatched threads will result in leaks.

Rating Assess Pressure Ratings

Look for the maximum PSI rating before purchasing. Standard garden hoses usually require fittings rated for at least 200 PSI. Lower-rated fittings may burst under high water pressure or air compression.

Verify Review Included Accessories

Check if the kit includes necessary washers, O-rings, or wrenches. These small components are often sold separately and can add to the total cost. A complete kit saves time during installation.
