Jacuzzi – Drain Valve Cap with Gasket for Sundance and Jacuzzi J-300 J-400

The Jacuzzi 6540-039 is a replacement hot tub drain valve cap with gasket for Sundance Spas and Jacuzzi J-300 and J-400 spas. It is made to be used together with the drain valve cap 2540-303, so check both parts when you order a replacement.

Compatibility with Sundance Spas and Jacuzzi J-300 and J-400

This spa drain valve cap is listed for the following hot tubs:

• Sundance Spas hot tubs
• Jacuzzi J-300 hot tubs
• Jacuzzi J-400 hot tubs

The same part number, 6540-039, is used for both Sundance Spas and Jacuzzi. If your spa is a different model or brand, do not assume that this cap will fit, and compare the details with your current part first.

How to choose the right drain valve cap

The 6540-039 cap with gasket must be used together with the drain valve cap 2540-303. These are two separate part numbers, so look at your drain valve and confirm which of the two parts you need to replace.

Compare the part number and the measurements below with the cap you are replacing. A cap that looks similar but has different dimensions may not suit your drain valve.

Dimensions of the 6540-039 drain valve cap

Use these measurements to compare the new cap with the one on your hot tub:

• External diameter: 35 mm
• Thread diameter: 25 mm
• Height: 17 mm

Measure your existing cap with a calliper or ruler before ordering if you are unsure that it matches.

What is included

The part is supplied as a drain valve cap with gasket. The mating drain valve cap 2540-303 is a different part number and is not described as part of this item, so check whether you need it as well.

When you search for a replacement, use the Sundance Spas / Jacuzzi part number 6540-039 to find the correct cap quickly and avoid ordering the wrong part for your spa.
