Fit like a glove. Works perfectly. Directions were clear and easy to follow. Very happy to resurrect my old Weber Q300.

My Weber grill Q300 is roughly 10 year’s old and noticed the slow deteriorating performance of the old original regulator. At first I thought it was an issue with the propane tank but Webers excellent tech support set me straight. I was able to obtain this new OEM Weber regulator from Amazon the quickest at a fair price and had the grill back up and running in time for holiday cooking. This new updated regulator along with my new Weber burners seem to function better than ever before. Thanks Weber and Amazon!!

Wow, I’ve contacted Weber, and they told me that they didn’t have this manifold.So happy that I’ve found it on Amazon.Now I can use my old BBQ, for another 19 years.

Great way to add some life to an existing grille. Together with new burners, I think we will get another ten years of life out of this grille, at only about 1/4 the cost of a comparable new grille.

No me gusto porque tiene fuga de gas en la manguera, y como ocupaba solo el manipulador, no lo devolví pero el costo de la manguera lo perdí
