Ryobi 1 Gallon sprayer replacement pump rubber valve / seal esun TPE 83A
Description
replacement for rubber pump valve seal that becomes swollen acidity, I opened and cut it free so much the valve seal is butchered have no idea what the actual dimensions are supposed to be (pictured above), I also I am guessing the TPE I used has better acidity resistance, this TPE is made for resistance to oil and has really impressive heat resistance, its not what I am used to so I am betting this will work better as far as not swelling from acidity . This design works just as good as the butchered one that i had been using. I purposly made the neck of both flaps thinnner to simulate the pliability of the original rubber valve. esun TPE 83A 235C 50C 20mm/sec 100% fan 20% grid support.
