Parker 32PTC-10 Push-to-connect Union 5/8 Inch Od

Product Description

The PARKER 32PTC-10 is a push-to-connect union tube fitting designed for tube-to-tube connections in fluid and pneumatic systems. Constructed from composite material with a nitrile O-ring, it creates a reliable, leak-resistant seal without tools or threaded assembly. The fitting accepts 5/8 inch OD tubing on both ends and is rated for pressures up to 250 psi. It is typically installed by plumbers, HVAC technicians, and fluid-system mechanics in applications where quick, field-serviceable connections are required. The lightweight design weighs 0.06 pounds and ships as a single unit.

The 32PTC-10 is suited for residential and light commercial fluid distribution and pneumatic control systems. Its push-to-connect design makes it appropriate for retrofit and new-installation work where reducing assembly time is a priority. The composite body holds up well in environments where corrosion resistance is needed, and the nitrile O-ring provides compatibility with a range of common fluids and gases. This fitting is a direct inline union, meaning both connected tube ends must be cut cleanly and deburred before insertion to ensure a proper seal.

Key Features

• Push-to-connect design requires no tools, soldering, or threaded assembly
• Composite body for corrosion resistance in fluid and pneumatic applications
• Nitrile O-ring for reliable sealing across common media
• Rated to 250 psi operating pressure
• Accepts 5/8 inch OD tubing on both ends for inline union connections
• Lightweight at 0.06 pounds — minimal load on tubing runs

Compatibility

Designed as an OEM-style push-to-connect union replacement for systems using 5/8 inch OD tubing in fluid distribution and pneumatic control applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians depending on the system type. Before connecting, depressurize and drain the line completely. Tubing ends must be cut square and deburred to prevent O-ring damage and ensure a full, locking insertion. To disconnect, use the appropriate release tool or collar to depress the collet before withdrawing the tube.
