Your 14mm male piece sits in the adapter, and its 18mm male end goes into the 18mm female piece.
A simple straight adapter with a frosted 18mm male joint.
Sold in packs of 2, 3 or 4, so you have a spare if one breaks.
Soak in isopropyl alcohol, rinse with warm water and let it dry.

Your piece needs a 14mm male joint, and your water tool an 18mm female joint.

Gently push the frosted 18mm end into the 18mm female joint.

Set your 14mm male WPA or stem into the adapter's 14mm socket.
Check before you order: This adapter only works one way: 14mm female in, 18mm male out. Check that the piece you're connecting has a 14mm male joint (frosted on the outside) and that the piece it goes into has an 18mm female joint (a socket). It won't turn a male joint into a female one, and it won't fit other joint sizes.

Steps a 14mm male joint up to an 18mm female joint. It only works in that direction.

Review of 14mm WPA (Arizer)
Got these for my Solo Max. Fit perfectly, no leaks or wobble. Used with a beaker bong, works amazing. Smooth, easy to clean, and nice thick glass. Highly recommend.

Good strong glass. Smooth vapor and very portable.
Review of 14mm WPA (Arizer)
Wasn't sure if this would actually fit, but it works absolutely perfect on my Air Max and my Solo II. Super smooth vapor, easier on the throat. Couldn�t be happier!
Review of 14mm WPA (Arizer)
Good product. Works exactly like you'd hope. Tight fit, solid performance. Will buy again.
Review of Short Stem & 14mm WPA
Does the job but doesn't fit as tight as the stem that came with the device. I wouldn't trust the longer ones but these short ones work fine.
It joins a 14mm male glass joint to an 18mm female glass joint, for example a 14mm WPA going into a bubbler or water tool with an 18mm female joint.
The 14mm end is female: a socket that a 14mm male joint pushes into. The 18mm end is male: the frosted outside that goes into an 18mm female joint.
No. It only takes a 14mm male piece into an 18mm female piece. It can't connect an 18mm male piece to a 14mm female piece.
A male joint is frosted on the outside; a female joint is a socket. If the listing for your WPA or water tool gives the joint size, go by that. Otherwise measure across the joint: it will be close to 10mm, 14mm or 18mm.
Soak it in isopropyl alcohol, rinse it with warm water and let it dry fully before use.
