Frequently Asked Questions
Q:
What sizes does the John Guest CI3208U7S connect?
A:
It connects 1/4-inch OD tubing to a 7/16-24 UNS female thread used on compatible filtered-water faucets.
Q:
Is the 7/16-inch thread an NPT pipe thread?
A:
No. It is a 7/16-24 UNS straight thread associated with a 1/4-inch compression-style faucet connection. Do not substitute a 7/16-inch pipe fitting.
Q:
What tubing can be used with the quick-connect side?
A:
Use compatible plastic or copper OD tubing in the stated size, within the tubing and fitting pressure and temperature limits.
Q:
How do I prevent a leak at the faucet thread?
A:
Confirm the faucet stem uses the matching thread and sealing method, start the nut squarely by hand, and do not overtighten the acetal fitting.
Q:
How is the tube inserted and removed?
A:
Cut it square, push fully to the stop, and tug to check engagement. To remove it, depressurize, press the collet inward evenly, and pull the tube straight out.
Q:
What approvals and pressure limits apply?
A:
John Guest lists NSF 51 and NSF 61 for this fitting family. For 1/4-inch size it lists up to 230 psi at 68°F and 150 psi at 150°F; the 3/8-inch size is listed up to 150 psi at 68°F and 100 psi at 150°F.
