Frequently Asked Questions

No. This listing is for the Inlet Tube only. Hoses, strainers, and seals are sold separately unless stated otherwise on this page.

Check your sprayer’s parts manual for part number 187627. If listed as “Tube, Inlet,” it’s the correct OEM replacement. You can also contact us with your exact model and serial for confirmation.

A new OEM Inlet Tube can help restore proper sealing at the pump inlet, which supports faster priming and more consistent suction—especially if your old tube is bent, worn, or damaged.

Follow the Graco service manual for your model. Some assemblies use specific thread sealants or gaskets; over-application can affect sealing. Hand-start first to prevent cross-threading.

The 187627 is used across multiple electric airless models. If your unit isn’t listed above, share your exact model/series and we’ll confirm compatibility or recommend the correct inlet tube.
