Most listings include the manufacturer part number so you can match it to your equipment manual or the old part. If you are not sure which size you need, send us the make and model of your pump, filter or heater and our team will confirm the correct O-ring before you order.

Tip: Replace lid and union O-rings whenever you service a pump, and lubricate them with a silicone-based pool lubricant, never petroleum jelly. Need help? Call 725-205-1783 or pick up same day at our Henderson, NV store.
