Watts Aqualock push-to-connect male adapter joins 1/4" OD tubing to 1/4" male NPT threads with a quick tool-free push-in connection. The O-ring guide design seals on the tube OD for a zero-leak fit, and the fitting allows the tube to swivel under full pressure - useful in vibrating or dynamic installs where a rigid fitting would work loose. Typical uses at this OD include ice maker lines, humidifier feeds, RO water systems, and low-flow appliance hookups.

• Connection: 1/4" OD push-to-connect x 1/4" male NPT
• No tools, no tube inserts, no soldering required
• O-ring guide seal for zero-leak connections
• Tube swivels under pressure - tolerates vibration without backing out
• Works with PEX, polyethylene, polybutylene, and soft copper tubing
• Lead free brass body - certified for potable water (NSF/ANSI 61, NSF/ANSI 372)
• Rated for hot and cold water service
• Pressure rating: 150 PSI at 70 deg F, 50 PSI at 140 deg F

Tip: Cut tubing square (a tube cutter is best - a hacksaw leaves ridges that score the O-ring) and push the tube straight in until it bottoms out. To disconnect, press the collet ring against the body and pull the tube straight out. Mark the insertion depth with a pencil before pushing to confirm full engagement.
