5.5" Coloured Glass Diffuser Downstem

The 5.5" Coloured Glass Diffuser Downstem is a replacement glass downstem designed for compatible bongs and water pipes that use an 18 mm female joint and 14 mm male bowl setup. To help this product stand apart from plain clear replacement stems, the strongest title angle is the 5.5" length, 18 mm male to 14 mm female sizing, diffused tip, six colour options and gold “Fun” logo.

Made from high-quality coloured glass according to product details, this downstem adds a clean accent look while helping improve water bubbling through its diffused tip. Available in red, pink, purple, blue, green and grey, it is a practical replacement or upgrade part for customers who want better style matching and smoother airflow support in a compatible water pipe. Sold individually; colour may vary by selected variant or stock.

Main Feature: 5.5" Diffused Downstem with 18 mm to 14 mm Fit

The main feature of this downstem is its 18 mm male to 14 mm female fit. The 18 mm male joint is designed to fit compatible 18 mm female bong joints, while the 14 mm female opening accepts compatible 14 mm male bowls.

How It Works

This downstem inserts into a compatible bong or water pipe joint and directs smoke from the bowl into the water chamber. The diffused tip helps create extra bubbling as smoke enters the water, giving the piece more filtration support than a plain open-ended stem.

For replacement-part shoppers, the most important details are the 5.5" length, 18 mm male outer joint and 14 mm female inner joint. Customers should measure their current downstem before ordering to confirm the length and joint setup will fit correctly.

Who Is This For?

This coloured glass downstem is best for bong owners, replacement-part shoppers and glass accessory buyers who need a 5.5" downstem for a compatible 18 mm to 14 mm setup. It is especially useful for customers replacing a broken stem or upgrading from a plain clear downstem to a coloured glass accent piece.

The assorted colours make it a strong choice for shoppers who want their replacement part to match or contrast with their bong, bowl piece or existing glass setup.

How to Measure Your Downstem

To choose the correct replacement downstem, remove the old stem from your bong and measure from the bottom of the ground joint to the end of the stem. Do not include the bowl in this measurement.

Next, confirm the joint size. The outer joint size is the part that fits into the bong, while the inner joint size is the opening that accepts the bowl. This downstem is listed as 18 mm male to 14 mm female, so it is intended for compatible water pipes that use that setup.

Why Choose This Coloured Glass Downstem?

This product should be positioned around its 5.5" size, diffused tip and coloured glass finish, not just as another replacement stem. The colour options and gold logo detail give it more shelf appeal than a basic clear downstem, while the diffused tip adds practical function.

It is a strong cart add-on for customers replacing an old stem, buying a new bowl piece or refreshing a compatible bong. The 18 mm to 14 mm sizing should be clearly shown so customers can confirm compatibility before ordering.

Care Tips

Remove the downstem before deep cleaning your bong or water pipe. Rinse it regularly and use a suitable glass cleaner when buildup appears. Pay close attention to the diffused tip because residue can collect around small openings.

Rinse thoroughly after cleaning and allow the downstem to dry fully before reinstalling. Handle the ground joint carefully during cleaning and storage because replacement glass parts can be delicate.
