Low pressure charge port leaking

[Mr pogo]

back in the r12 days snap on tools sold a pricey gadget that could change out the core without losing the charge.
googling shows other companies now sell similar tools, one I looked at was in the low $30s.

Alright, I guess I'll try to replace the schrader valve first. On Rockauto, there are three choices:

FOUR SEASONS Part # 26775 $8.68
Caps and Valve Core Seal Kit; w/ Hi-Side Primary Seal

FOUR SEASONS Part # 26779 $11.34
Caps and Valve Core Seal Kit; w/ Hi-Flow Valve Cores

FOUR SEASONS Part # 26778 $25.79
Caps and Valve Core Seal Kit; w/ Areoquip Fittings

Anyone know the difference besides the price?

The shcrader valves I use are:

ACDelco 15-1119 Schrader Valve - for the low side



ACDelco 15-5438 valve - for the high side

Some parts list both part descriptions as heater control valves. F if I know why they did that. Ive used both parts w.o. any problems. Rock auto lists the parts under heating and AC- Schrader Valve. The Low side valve core is around $5-9 dollars on the net, yes its a rip off for a $.30 cent part. Who knows, a tire valve stem core is probably the same part, however the AC valve looked like it had more robust seals on it.



Replace the HS fitting when performing AC repair. Its cheap leak free insurance.


I don't now about the four seasons parts
