HAKATOPO-Ring Kit For Senco Framing Nailer FramePro 701-XP 702-XP 751 752 600

The two LB3505 O-rings that fit in the check valve are too small and nail gun will not work with them installed. I suspect they are also made of the wrong type of material. The OEM rings are made from an oqaque whitish material, and the ones in this kit are black? Senco uses regular black o-rings in other placed, but on things that "move" a lot, they use a different material for the 0-rings.None of the o-rings are labled, and if the ones you currently have are broken/deteriorated, you'll have nothing to compare for size... the o-rings on the trigger valve (3 of them) all look very similar, but definitely need to go in the correct places. For the price, each o-ring should have the part number attached. A couple of the o-rings were also out of shape due to being stuffed in a plastic bag for shipping. Unfortunately for me, of the 3 o-rings I absolutely needed, the two LB3505's didn't fit correctly. Complete waste of my time!

Bought this kit hoping to freshen up my Senco frame fro 701xp. Most of the o-rings dont fit lile they are suppossed to. They are too small, specially the firing valve inner and outter seals. I ended up using about 5 seals total.I do not reccomend it!

I used this kit on a senco 600. Once it was reassembled it would not fire a nail. When I pulled the trigger it would blow air out the trigger assembly (It wasn’t doing that before). O-rings LB3505 were too small so I had to put the old ones back in for the gun to work. The other o-rings worked fine.

Kit had all parts needed for rebuild but I only needed two. Got me back to project with fast shipping

They all did not fit had to order more O ring part for the gun , should have been in gun kit
