MAINTENANCE / CMM
Works great. It is a good idea to change these out every few years. I used the Ez Turn Lubricant as a sealer and it worked great. Be careful not to tighten them too much as the valve will become stuck.
Exactly what we needed.
Needed to replace 2 leaking drain valves on Piper Cherokee Six. Ordered these from Aircraft Spruce. Great product, Worked as advertised.
Very good product and Service yo the client. Thank yoy best regards
Perfect fit and function. It is very difficult to get these things lined up to go into the wing, especially if gas is coming out while you are trying to put it in. Completely drain the tank or prepare to be gased.
Standard part and arrived quickly
As another Dave said these things are just part of flying a plane. I keep 2 spares in my plane as it doesnâ€™t take much for them to start leaking. I would advise carrying vise grips as wrenchâ€™s will strip that brass fitting.
Perfect fit. Works well. Used on Zenith CH 200 with Lycoming 0-320 E3D 150 hp.
Are just What I needed.
Per the manufacturer, replacement seals for these drain valves are no longer available. We do not recommend that they be overhauled. Replace the valve if it begins to leak.
Additionally, the valve is not recommended for halogenated hydrocarbons, nitro hydrocarbons, Phosphate ester hydraulic fluids, automotive brake fluids, ketone, ethers or alcohols. Fuels with additives such as alcohol or ether can cause premature deterioration of the seal rings.
CCA-1250 is spiral, twist open and CCA-1550 is push to open, turn to lock and conforms to NSN 2915-00-202-6420 when CCA-1250 does not.
This does not accept an o-ring and only accepts a seal. The seal is built in to the valve.
This valve is gravity fed so there is no operating pressure that it pushes fluid out. However, this has been has been tested at 40psi if fluid was to push through the valve.
The drain valves are made of brass.
They recommend a Teflon tape or EZ-turn (fuel lube) type liquid sealant.
