Good fit, seems to make a good seal .

Hasn't leaked yet. There's only really two places you can source your gaskets, sensors , o rings and other quality parts. Eveyone knows Riff Raff is one.
I quit buying crap from others a while ago and only use riff raff. If I'm gonna spend all weekend working on something I want it to go as smooth as possible and I don't want it to fail prematurely.
The only thing thats bad for me is they're in Oregon and I'm in Florida...... so I'm about as far away from them as I can be , but shipping was still fast and I had my parts in about 5 days. So pretty good actually.

This outlet O-ring was very much needed to complete my job to get my truck up on the road. Great customer satisfaction, knowledge and expertise

Perfect fit, form and function. Great delivery and packaging for shipment.

Definitely will recommend buying from you guys

Hard to find but thankfully Riffraff has everything. Worked perfect and fixed the boost leak.

Good upgraded oring, and seals better than the original.

Worked much better than my oem square o ring, i was losing all boost cruising, the gauge read 0 psi. and almost 15 psi wide open throttle. hits 32 psi and holds it now!

My original seal was starting to get stiff. Replaced it with this item and the seal is great. Original is a flat seal and this item is a true O-ring. Thank you!
