Thermaltake Pacific DIY OD 16mm Bending Kit CL-W093-AL00BL-A
The Thermaltake bending kit is designed for 16 mm OD PETG tubes, enabling near-perfect bends essential for tight, clean radiator-to-block loops. It includes mandrels for 45/90/180/360-degree bends and a professional-grade pipe cutter for bevel-ready cuts, improving fitment and reducing leaks in rigid-loop builds.
Dracaena.io 16 Pack PETG Hard Tubing – Blue
This PETG tubing from Dracaena.io offers 14 mm outer diameter with a 10 mm inner diameter, providing robust rigidity for hardline setups. PETG is known for better impact resistance than acrylic and is non-toxic. The 450 mm length is suitable for mid-to-long loops, and five color options—including blue—enable color-coding for airflow or coolant pathways.
Dracaena.io 16 Pack PETG Hard Tubing – Green
Green PETG tubing provides the same structural benefits as blue variants with a distinct hue for visually organized builds. The 14 mm OD / 10 mm ID configuration ensures reliable compatibility with 16 mm system components and fittings. Green is ideal for color-moding coolant paths or to match a themed build.
Dracaena.io 6 Pack G1/4″ to 16mm Compression Fittings – White
These G1/4″ compression fittings with a 16 mm outer diameter target 16 mm hard tubing, offering compatibility with common acrylic, copper, brass, and stainless steel lines. The design prioritizes quick installation and a secure, durable fit, with a 4.5 mm male thread length that helps ensure a snug connection in rigid-loop systems.
PrimoChill 3/8in. ID x 1/2in. OD Rigid PETG Tubing – 6 Pack
PrimoChill’s rigid PETG tubing is designed for beginner-friendly hardline builds, offering easy cutting, bending, and length adjustments. PETG tubing is durable and transparent, making coolant flow and potential air pockets easier to inspect. The 6-pack provides an ample quantity for standard or dual-loop configurations, with clear visibility for coolant level and flow checks.
Buying Guide: Key Purchase Considerations for Hard Pipe Water Cooling
- Tube material: PETG is popular for rigid tubing due to impact resistance and ease of bending with mandrels; polycarbonate (PC) tubes offer high clarity and stiffness but can be more brittle under impact. Your choice affects ease of installation and long-term durability.
- Diameter and compatibility: Most 14 mm OD PETG tubes pair with 16 mm fittings for rigid-loop setups. Verify outer and inner diameters to ensure seamless compatibility with your fittings, reservoirs, and water blocks.
- Bending tools: Mandrel sets reduce kinks and ensure consistent bends. If you plan tight radii, a bending kit is essential to maintain smooth coolant flow and reduce leakage risk.
- Fittings and compression: G1/4″ threads are common; choose fittings that match your tubing OD and actuation style. Compression fittings provide strong seals for high-pressure loops and make future upgrades easier.
- Aesthetics vs. practicality: Color options (blue, green, white) help with color-coded loops and cable management visuals. Consider color themes that align with your build’s overall design.
- Color consistency and availability: Some lines come in multi-pack sets with fixed color options. If you want uniform color across all segments, select a single brand and color family to avoid mismatches.
- Installation skill level: Rigid tubing demands precise cuts and careful fitting; beginners should start with a bending kit and basic fittings before expanding to more complex loops.
- Maintenance and leaks: Inspect joints for tightness after initial setup. Routine checks help prevent coolant leaks and ensure long-term reliability of a hard-pipe loop.
Hard pipe water cooling provides a sleek, durable cooling system with minimal clutter. The combination of a bending kit, color-tuned PETG tubes, and reliable compression fittings helps ensure a clean, professional finish for high-performance PCs.
