Pesado HD - High Diffusion Gaggia Classic Shower Screen

Introducing the Pesado High Diffusion shower screen. Designed for precision and consistency, eliminating the main issues causing irregular extractions.

Uneven water distribution has always been an issue when trying to achieve consistent extractions, this can be caused by the irregular water flow path through mesh shower screens, smaller surface area coverage and uneven puck infusion. Utilizing 18 channels we can target the exact spots every extraction, resulting in consistent water flow between every shot.

Combined with the unique feature of the outer channels running all the way to the edge of the shower screen, controlling water flow to target the entire puck bed right to the basket edge, giving us complete control over our water diffusion every shot.

Seal Compatibility Notice:

When installing Pesado HD (High Diffusion) Shower Screen, you may notice that your portafilter feels slightly loose. Don’t worry, this is completely normal. The HD screen is specifically designed to work best when paired with the HE (High Extraction) baskets - for the best coffee experience.

If you're not using an HE basket and prefer your portafilter to lock in closer to the 6 o’clock position, here are a few easy solutions:

A. Use a shim behind the group seal.
You can purchase pre-made spacers or DIY your own using household paper materials, adjusting thickness as needed.

B. Try a thicker group seal.
Group seals are available in small size increments (typically 0.5mm or 1mm). 

C. Upgrade to a HE Basket
Pair your HD screen with Pesado HE basket for the perfect fit and performance.

The HD Shower Screen Built for the Gaggia Classic Family The Pesado HD High Diffusion Gaggia Classic Shower Screen brings the full 18-channel precision diffusion system to the Gaggia Classic group head — one of the most popular platforms in the home espresso market, and one where aftermarket shower screen upgrades consistently produce measurable improvements in extraction consistency. If you're running a Gaggia Classic, Classic Pro, Classic Evo, Classic E24, or Classic Pro E24, this is the correct HD screen for your machine. The same 18 precisely machined channels that run across the full Pesado HD range deliver water to the same locations every extraction, with outer channels reaching edge-to-edge across the full 58.35mm surface to ensure uniform puck saturation from the first drop.

Why the Gaggia Classic Benefits Particularly From This Upgrade The Gaggia Classic's stock shower screen is a mesh design — functional, widely used, and widely upgraded by serious home baristas for exactly the same reason as any other mesh screen: the water path is inherently variable. Mesh geometry means flow distribution changes subtly with scale buildup, cleaning state, and minor pressure fluctuations, making shot-to-shot repeatability harder to achieve. The Pesado GA-HD screen's channel system eliminates this variability by directing water through fixed, machined paths on every extraction. Combined with the 58.35mm diameter — significantly wider than standard Gaggia screens — coverage extends to the full basket wall rather than leaving the outer portion of the puck under-saturated.

What's Included and the Seal Compatibility Note The GA-HD set includes one 58.35mm HD shower screen (304 stainless steel, 3mm thick, 18-channel) and one GA-HD diffusion plate. Your existing shower screen screw is used for installation — no additional hardware required. Seal compatibility notice: the 3mm thickness of the HD screen may cause your portafilter to lock in slightly looser than standard — this is normal and fully resolves when paired with the Pesado He[%] High Extraction Basket (recommended for the best fit and performance). If you're not using an HE basket, a thicker group seal or a group head shim will restore the standard lock position.
