Pxyelec 3/8 inch Bulkhead Quick Connector, 1/4 inch White Tube Fittings Bulkhead Connector for RO Water Reverse Osmosis System (Pack of 20)

Cant beat the price. Quality is average or slightly above. Fits 5/8 (16mm) panel hole for 1/4 and 13/16 (21mm) for the 3/8. Used some automotive A/C rubber/metal sealing washers to attach to the side of a plastic tote. Working well!

Worked perfect

You get what is promised and it works well

S est ok

as shown

Perfect for my use!

Very easy to use and the value is totally unbeatable in comparison to the big box hardware stores. The plastic might not seem to be as thick as the the name brand ones sold elsewhere but these have saved me a bundle and havent let me down so far! I would definitely purchase this again.

good quality

Works as expected. No leaks in my lines

These items are great but they absolutly dont work without rubber washers. No idea why somone would sell these without the washers. But you can get the washers sepertaly somewhere else. Just look for 3/4 ID rubber washers
