About this Product

Product SKU: A19MX

Sometimes you need an adapter to change the gender of a joint when putting together a custom rig.  If you're trying to make your water pipe compatible with different accessories, you must have an adapter or two.

This GRAV 18.8mm Male to Male Angled Joint Adapter made of durable glass changes a 19mm female joint into a 18.8mm male joint.  This adapter is also angled, for converting a 45 degree joint into a 90 degree joint. 

Like you'd expect from any GRAV product, this adapter works very well and it features good quality glass and fine craftsmanship.  This adapter will fit snug with no leaks. It's a piece you can depend on for years.
