Product details

Pentair 70429 is the hex head bolt used on several Pentair pump families, in 3/8-16 x 3/4 inch. It is the genuine Pentair fastener, not a hardware store substitute.

Where it is used

Pentair lists this bolt for the IntelliFlo VS3050 and VF variable speed pumps, the WhisperFlo WF and WFE pumps, and the R Series commercial pumps in the 5 to 15 HP range. The same size covers all of them.

Why the right bolt matters

Pump bolts live outdoors in wet, chlorinated air, and they are usually the first thing to seize or round off when a pump is opened for a seal or impeller job. Fitting the specified size and thread means the bolt pulls the housing down evenly and does not chew the threads it goes into. It is worth replacing any bolt that fights you on the way out while the pump is already apart.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this bolt?
It is a 3/8-16 x 3/4" hex head bolt, the size Pentair specifies as part 70429.
Which pumps use it?
It is listed for the Pentair IntelliFlo VS3050 and VF, the WhisperFlo WF and WFE, and the R Series commercial pumps from 5 to 15 HP.
Is this one bolt or a set?
This listing is the single Pentair 70429 bolt. If your pump uses several, order the quantity you need.
Should I replace all the pump bolts at once?
If one is corroded or the head is rounded, the rest have usually seen the same water and weather. Changing them together while the pump is apart saves a second teardown.
