Sleep Number O ring

Weíve got a Sleep Number bed that is less than a year old and itís losing air when connected to the pump. It does hold air with the white cap on it. I though it was a bad pump, which I talked with SN about, and have been waiting on a new pump for over two months now.

I put a different pump on it last night and it still leaked, so now Iím wondering if itís the O ring which I want to get while Iím out. Iíve looked online and canít find the size anywhere. Does anyone happen to know? As a last resort I can take one off and try to find a match.

I was able to reach a knowledgeable CS rep at SN. She couldn’t give me the direct size, but they are SAE AS568B size -011, which equates to 5/16 ID, 7/16 OD, 1/16 thickness.

I would try some silicone lube on the o-ring firstÖ. it might soften it a little and seal it right up.Click image for larger version
