PSRU Seal

[Jeroen van den Berg]

This topic is meant to share our experiences with the PSRU seal.

When did you encounter issues with the PSRU (after how many flight hours/years)?

Where did you order a new seal?

 

Did you have issues installing it?

Chad gave some valuable feedback on the Facebook Page regarding the sizes of the PSRU seals, copy-paste below:

Note to everyone, the part number supplied by harold will not fit most of the psru’s. Harold has one of only about 5 or so psru’s that run on a single 8 in wide belt. The size of his seal is 105 OD, 70 ID, 10 thickness.
If you are running a psru with a dual belt system, you need yours to be 100/70/10 or 100/65/10. Can’t remember exactly, but the dimensions will be stated on the seal itself.

Hi All. A quick note on PSRU seals. I blew the lower input seal on my LS3 PSRU. It is an SOG seal from Taiwan. Apparently common in Au but not so common around these parts. SOG has a website where you can ask for info.
I eventually got a contact in Edmonton who brought a pack in for me. Their name was Daemar (see this link)
I think they have offices around North America but check the website to be sure. Or send SOG a note on their contact page and they’ll steer you in the direction of a local distributor.

Part number is 7010510-DL-V. Not super expensive unless you’re in the middle of nowhere or heading for a fly in and it starts to leak.
Make sure you get the Viton ones. They’ll tolerate the heat a bit better.
