## Summary description

Perfexim brass straight union coupling with O-ring, 3/8" size (MPN 07-146-0100-000). A mechanical fitting for joining two pipes or hoses in a straight line, featuring an integrated O-ring for sealing. Suitable for fluid and gas installations where a compact, leak-resistant brass connector is required; used in plumbing, HVAC, and hydraulic low-pressure systems.

## Long description

Perfexim brass straight union coupling with O-ring 3/8" is a compact mechanical fitting designed to join two pipes or hoses in a straight line. Constructed from brass and fitted with an integrated elastomer O-ring, the coupling provides a sealed connection suitable for low-pressure fluid and gas installations. The 3/8" size makes it appropriate for many plumbing, HVAC and hydraulic applications where a small, robust, and corrosion-resistant connector is required.
Advantages
The brass construction offers good corrosion resistance and mechanical strength while remaining relatively easy to install. The integrated O-ring ensures a reliable, leak-resistant seal without the need for additional sealing tape or compound. The straight union design allows for a direct, inline connection that maintains flow characteristics and simplifies alignment of piping runs. Its compact dimensions make it suitable for installations in confined spaces.
Suitable for
 Domestic and commercial plumbing systems
 HVAC refrigerant and condensate lines (low-pressure applications)
 Low-pressure hydraulic circuits and pneumatic lines
 Appliance connections and serviceable joints
Key specifications
 Material: brass body with elastomer O-ring sealing
 Connection type: straight union coupling for inline joining
 Nominal size: 3/8"
 Sealing: integrated O-ring for leak-resistant performance
 Operating environment: suitable for fluids and gases at low to moderate pressure
 Installation: push-fit or threaded depending on mating components (compatible with standard 3/8" fittings)
How to use
Ensure mating pipe or hose ends are clean, free of burrs and correctly sized for a 3/8" union. If the mating components are threaded, confirm thread compatibility and engage threads by hand before tightening with an appropriate wrench; avoid over-tightening to protect the O-ring. For push-fit installations, insert the pipe fully until it reaches the stop and check the seal. After installation, pressurize the system gradually and inspect the joint for leaks. Replace the O-ring if signs of wear, hardening or damage appear during maintenance.
Usage recommendations
Use the coupling within the manufacturer's recommended pressure and temperature ranges for brass and elastomer seals. Avoid exposure to aggressive chemicals or media known to degrade the O-ring material. During maintenance, inspect both the brass body for corrosion and the O-ring for elasticity; replace components that show deterioration to maintain a reliable seal.
