Waterway - Top-Load Filter Lock Ring Without Tab - CSFILT1401

Waterway – Top-Load Filter Lock Ring Without Tab

The Waterway CSFILT1401 is a replacement hot tub filter lock ring without tab, made for Waterway Top-Load and In-Line filters. It holds the filter cover in place against the water pressure inside the filter. Unlike the more common version, this spa filter lock ring has no spring-loaded tab.

Compatibility with Waterway Top-Load and In-Line filters

This lock ring is designed for Waterway Top-Load and In-Line filters. It is fitted to some spas manufactured by Coast Spas and Cal Spas.

Before ordering, look at the ring on your filter. If it has no tab and is the plain, tab-free style, this is the version you need. The Waterway part number for this item is CSFILT1401.

Lock ring without tab or with tab: how to choose

Waterway also makes a second version of this lock ring. That version has a spring-loaded tab which keeps the ring in place once it has been tightened correctly. It is used by many other spa manufacturers and is much more common overall.

The ring on this page is the version without the tab. If your current ring has a tab, you probably need the Waterway Top-Load filter lock ring with tab instead. Compare the two designs with your existing part so that you order the matching one.

What the filter lock ring does

The lock ring sits on the filter housing and holds the cover down. This is important because the water inside the filter is under pressure and pushes against the cover. A cracked, worn or missing ring is therefore a good reason to replace it.

Dimensions

Check these measurements against your old ring when you are choosing a replacement:

• Height: 35 mm
• External diameter: 190 mm
• Internal diameter of the thread: 175 mm

The internal thread diameter is the measurement that matters most when you compare the ring with the filter housing it screws onto.
