Fast Fab vs JayCee Spring Push Rod Tubes

[DesertG]

I see the Fast Fab's have a stainless steel washer on both ends of the tube as a backing to help keep the rubber seal seated.

The JayCee only has a washer backing on one end.

Which set should I get.

Thank you!

I use the FastFab…high quality

Unfortunately no experience with Jaycee’s tubes

I have original JayCee tubes before EMPI so I can't speak to the latest ones, but my originals have been leak free and came with washers for both ends. I did replace the o-rings this last time because they were getting a little wear from removal and install and I used Nitrile 22mm OD 2mm width. Be sure and use a little lubricant on the o-rings.

Thank you. Maybe I am missing something but if I look at Jaycee, the one end of the tube is not machined to take a washer

I have this set from CB. Very nice, adjustable width. Uses stock seal in center. Large ID. No leaks.

I bought the Fast Fabs in 2019, used them on 3 different engines.

I imagine they are the same design as Jaycee, but anodized.

Seems like the most common reason for leaks now is the seal cut at the heads…not a pushrod tube problem.

Since I am in between engines, I pulled one out of the drawer.
The JayCee's I have have 2 different size valve spring shims for washers.

Those are just valve spring shims. Jaycee/Empi now provides a stainless washer in the kit. The valve spring shims you have are wider then the washer they currently provide so it supports the seal better (obviously you have 2 different shims-I would use the widest necessary to support the entire pushrod tube seal.
