Important Product Identification

This Listing Is for the Gasket Only

Part 39-P900-04 identifies the cassette gasket used with a compatible
PAL-2000RU light assembly. It is not a replacement light, lamp, cassette
or lighting conversion kit.

PAL lighting systems include multiple seals and service components that
may appear similar. Confirm the complete part number and the existing
light model before sourcing remaining old stock.

Important:
Do not order a gasket based only on its apparent diameter, shape or
color. Underwater light seals must match the intended fixture and
cassette configuration.

Installation and Service Guidance

Underwater pool and spa lighting involves electrical equipment installed
in or near water. Disconnect power at the appropriate breaker and verify
that power is off before removing or servicing the light.

Confirm the existing fixture is a compatible PAL-2000RU model
Verify the complete gasket part number before installation
Inspect the cassette and mating surfaces for damage
Remove debris and old gasket material from sealing surfaces
Do not use a gasket that is stretched, cut or permanently distorted
Seat the replacement evenly without twisting or pinching it
Inspect retaining components before reassembling the light
Follow the fixture manufacturers service instructions
Test the completed assembly before returning it to normal use

Replacing a gasket may not correct a problem caused by a cracked cassette,
damaged lens, distorted retaining component or deterioration elsewhere
in the light assembly. Inspect the complete fixture during service.

Frequently Asked Questions

Is PAL Lighting 39-P900-04 still available?

This part has been discontinued and is no longer available through
Aqua Terra Backyard. This page remains online to help identify the
gasket and its original application.

What is PAL part 39-P900-04?

It is the replacement light-cassette gasket or seal identified for
compatible PAL-2000RU underwater light assemblies.

Which PAL light uses this gasket?

Product records identify 39-P900-04 for the PAL-2000RU light
assembly. The exact fixture label should still be checked before
sourcing or installing any remaining gasket.

Does this include the complete PAL-2000RU light?

No. This listing is for one cassette gasket only. It does not include
the complete underwater light, lamp, LED cassette, lens, cable,
transformer or controller.

Is item number 387998 the same product?

Yes. Distributor listings cross-reference item number 387998 with
PAL manufacturer part number 39-P900-04.

What is item number 57-330-1017?

It is a common distributor item or catalog number associated with
PAL light cassette gasket 39-P900-04.

Can I reuse the original light gasket?

A gasket that is flattened, stretched, hardened, cut, pinched or
otherwise damaged should not be reused. The complete light assembly
should be inspected before reassembly.

Is this gasket universal for PAL pool lights?

No. It is identified for a specific PAL-2000RU cassette application.
Other PAL light families may use different seals, gaskets or fixture
construction.

Can this gasket fix water inside the light?

It may be part of the required repair when the original cassette
gasket has failed. Water intrusion can also result from damage to the
cassette, lens, cable entry, retaining components or another sealing
surface.

Should a pool light be professionally serviced?

Service should be completed by a qualified professional when the
repair involves underwater electrical equipment, uncertain fixture
condition or possible water intrusion.
