SITA UV Replacement Sleeve Bolt - New and Old Design

SITA UV Replacement Sleeve Bolt — New and Old Design

This is the genuine sleeve bolt that secures the quartz sleeve and lamp connection on SITA domestic, LCD and LCD PLUS UV systems. It's supplied to match either the older smooth slide-on lamp connection or the newer locking design — check which your system uses before ordering, since the two aren't interchangeable.

Which design do you have?

Older Sita systems have a smooth lamp connection that simply slides on. Newer systems use a locking sleeve bolt design instead. If you're also replacing a power supply built for the newer locking design, you'll need this newer-style bolt fitted for the connection to work correctly. See our additional product photos for a visual comparison if you're not sure which design your system has.

Signs you need this part

• The existing bolt is cracked, corroded, or won't hold the sleeve securely
• You've noticed a small leak or looseness around the lamp connection
• You're fitting a replacement power supply built for the newer locking design and your system currently has the older type

Why it matters

A worn or incorrect sleeve bolt can let the lamp connection work loose or let water reach the electrical connection, so it's worth replacing at the first sign of wear rather than waiting for a failure.

How to fit it

1. Isolate water and power to the UV system before starting.
2. Remove the lamp and quartz sleeve as per your system's manual.
3. Remove the old sleeve bolt and check the O-ring or seal underneath for wear.
4. Fit the new sleeve bolt of the correct design for your system.
5. Refit the sleeve and lamp, then restore power and water and check for leaks.
