What Is the Cylinder Pre-cooler with 6-Arm Tree Perc Amber?

The Cylinder Pre-cooler with 6-Arm Tree Perc Amber by Blaze Glass is a compact, handmade glass accessory designed to sit between your bowl and your bong, cooling and filtering your smoke before it ever reaches your lungs. Pre-coolers — sometimes called ash catchers — serve a dual purpose: they trap ash and particulates so they never enter your main piece, and they add an extra stage of water filtration to drop the temperature of your smoke for a noticeably smoother experience. This particular model features a striking amber coloured glass finish that sets it apart from standard clear glass accessories, making it as much a display piece as a functional upgrade.

The 6-Arm Tree Percolator — Maximum Bubble Diffusion

At the heart of this pre-cooler is its 6-arm tree percolator. Positioned at the base of the internal diffuser downstem, the tree perc splits your smoke into multiple smaller streams simultaneously, generating a dense cluster of fine bubbles. The greater the surface area of smoke exposed to water, the more effectively heat and unwanted particles are stripped away before you inhale. The result is a hit that feels noticeably cooler, softer on the throat, and cleaner in taste compared to using a bong alone. If you are looking to genuinely upgrade the quality of every session without investing in an entirely new piece, adding a well-engineered pre-cooler like this one is one of the most cost-effective steps you can take.

Joint Configuration and Compatibility

The cylinder pre-cooler with 6-arm tree perc is built around a standard joint system that makes it compatible with the vast majority of bongs available today. The top of the unit features an 18.8mm female joint, into which a diffuser downstem is fitted. That downstem carries the 6-arm tree perc at its lower end, submerging it in water for full diffusion. At the bottom of the pre-cooler sits a 14.4mm male fitting, which connects directly into your bong. This 18.8mm-in, 14.4mm-out configuration is extremely common and means this accessory will work seamlessly with a wide range of setups. Blaze Glass also include an 18.8 to 14.5mm adapter in the box so you have additional flexibility if your bong uses a slightly different joint size. If you are interested in other ash catching and cooling options, you may also want to browse the Hurricane Catalyst WAM Ash Catcher 14.5mm or the Grav Labs 6in Upline Ash Catcher 45 Degree Red for alternative styles and joint angles.

Handmade Amber Glass and Coloured Joints

Blaze Glass are well regarded for the quality of their handmade borosilicate pieces, and this cylinder pre-cooler is a fine example of their craft. The amber tint runs through the body of the cylinder, giving it a warm, distinctive look that stands out beautifully when light catches the glass mid-session. The joints are finished in matching coloured glass rather than plain clear, adding a cohesive, considered aesthetic to the whole unit. A Blaze Glass logo is printed onto the base of the cylinder, completing the premium look. Each piece is made by hand, which means there may be very slight variations between individual units — a hallmark of genuine artisan glasswork rather than mass-produced alternatives.

Keeping Your Main Piece Cleaner for Longer

One of the most practical benefits of using a cylinder pre-cooler in your setup is the impact it has on the cleanliness of your bong. Because the pre-cooler intercepts ash and resin before they travel further down the line, your primary water pipe stays cleaner between sessions. Cleaning a small pre-cooler is far quicker and easier than a full deep-clean of a larger bong. For keeping all your glass in top condition, take a look at Namaste Cleaning Wipes Pack of 10 Isopropyl Wipes, which make light work of residue on glass joints and percolators.

What Is in the Box

Blaze Glass include everything you need to get started straight away. In the box you will find the cylinder pre-cooler with amber glass body and 6-arm tree percolator, one 18.8mm male glass bowl that matches the coloured joint aesthetic of the pre-cooler, and one 18.8 to 14.5mm adapter to ensure broad bong compatibility. This means there is no need to source additional components before you can use it — simply attach it to your bong, fill with water to the appropriate level, and enjoy an immediately improved smoking experience.

Who Is This Pre-cooler Best Suited To?

This piece is ideal for anyone who already owns a bong with a 14.4mm or 18.8mm joint and wants to noticeably improve the smoothness and cleanliness of their hits without replacing their entire setup. It is equally well suited to seasoned glass collectors who appreciate handmade amber glass as an aesthetic choice. If you are building out a more advanced water filtration setup, you might also consider pairing your bong with a Cooling Glycerin Attachment 19mm Green Grav Labs for an additional layer of temperature reduction on top of what this pre-cooler already delivers. The Cylinder Pre-cooler with 6-Arm Tree Perc Amber is priced at £14.95, making it one of the most accessible quality upgrades available for your smoking setup.
