I'm not sure if our Series 351 is the best match. It looks like your nylon fittings have wings. Can you confirm? If so, our Series 385 might be better.

the top part [bottom photo]does have wings ,the bottom does not .would that be the series 385? thanks lee

after looking closer I think the series 395 is spot on. Holding the part against the screen looks like a match. The wings on top stick out from metal about 1/8 of inch. Bottom is flush .how does this line up with the 395 series?
once again thanks for all your help. lee

Ah, I see. Then yes, if the top attachment does have wings but the bottom does not, then the Series 395 would be the best match.
