Metric 63mm to 2in Imperial PVC Adapter
SKU: ROP-BM63
- Seamless System Cross-Over: Eliminates diameter mismatch limitations by adapting international 63mm hardware outlets over to local standard 2-inch US PVC pipe lines.
- Low-Profile Bushing Integration: Engineered as a compact, space-saving socket bush that nests directly inside metric fittings to minimize total pipe run footprints.
- Heavy-Wall Rigid Configuration: Molded from premium, industrial-grade unplasticized PVC (uPVC) that effortlessly matches the burst tolerances of Schedule 80 systems.
- 100% Aquarium and Reef Safe: Formulated entirely from non-leaching, chemically inert polymers that will not drop toxins into sensitive marine environments.
- Standard Solvent-Weld Jointing: Integrates permanently using standard PVC primers and solvent cement for a zero-leak, high-pressure structural bond.

Reef Octopus Metric 63mm to 2-Inch US Standard Imperial PVC Adapter
The Reef Octopus Metric 63mm to 2-Inch US Standard Imperial PVC Adapter (SKU: ROP-BM63) is an authentic structural integration component engineered by Reef Octopus to streamline high-volume plumbing adaptations, eliminate custom piping headaches, and protect structural flow dynamics in large marine reef aquariums, central filtration systems, and specialized filtration loops. High-capacity European reef equipment—such as commercial-grade protein skimmers, primary tank drains, large UV sterilizers, and heavy-duty utility pumps—is built natively to meet metric plumbing specifications. In North America, locating local piping assets that mate with a metric 63 mm fitting is incredibly difficult. Forcing parts together with flexible vinyl plumbing or rubber coupling boots can lead to sagging or leaks over time, and heating PVC with a torch creates weak spots prone to catastrophic failure. This precision-molded solvent bush solves this problem cleanly, creating a seamless bridge to standard local 2-inch piping networks.
Manufactured to meet tight industrial engineering guidelines, the ROP-BM63 acts as a structural reducing sleeve. The outer diameter is specifically machined to slip natively inside a standard metric 63mm female socket fitting (such as a 63mm elbow, tee, or union block). The interior diameter is concurrently molded to accept a piece of standard US Imperial 2-inch Schedule 40 or Schedule 80 PVC pipe. By anchoring into your existing plumbing layout via standard solvent welding, it establishes a permanent, airtight connection that can withstand persistent high-pressure pump loops and system vibrations without fracturing or leaking.
Key Features
Maintains Maximum Flow Performance: Features a smooth internal transitional slope that eliminates dead zones, prevents detritus collection, and lowers head-pressure drag.
Resists Aggressive Chemical Corrosions: Heavy-wall construction stands up to continuous saltwater exposure, aggressive ozone injection paths, and acidic cleaning flushes.
Saves Critical Cabinet Real Estate: Unlike bulky external step adapters, this space-saving insert bush sits tucked entirely inside the host fitting to fit tight spaces easily.
(Note: This retail SKU contains (1) standalone 63mm-to-2" step adapter bushing. Direct metric piping lines, imperial socket fittings, PVC solvent cements, and high-volume pump housings are sold under separate product categories).

- Dry-fit your components first. Verify that the outer surface of your ROP-BM63 adapter slides smoothly into your metric 63mm socket fitting, and your US 2-inch pipe slides into the inside track.
- Use a piece of fine-grit sandpaper or a pipe deburring tool to lightly rough up the gluing surfaces on the adapter, the inside of the metric fitting, and the outside of the US pipe.
- Wipe all prepared joint areas clean with a dry cloth to remove any lingering plastic dust, oil films, or moisture.
- Apply a liberal, even layer of standard PVC primer to the outer 63mm barrel of the adapter and the inside sleeve of your metric receiver fitting.
- Apply a layer of high-strength PVC solvent cement over the primed zones, push the adapter firmly into the metric fitting with a quick quarter-turn twist, and hold tightly for 30 seconds.
- Repeat the priming and cementing process on the inner 2-inch track of the adapter to anchor your US Imperial pipe section. Allow the completed joint to cure fully for 24 hours before filling with water.
Pro Tips:
- Remember: This Adapter Nests Inside a Metric FITTING, Not Directly onto Metric PIPE.
CRITICAL ARCHITECTURAL PLUMBING RULE: When mapping out your pipe runs, keep in mind that the metric 63mm side of this adapter is a spigot (male) connection profile. It is specifically engineered to slide straight inside a 63mm metric socket fitting (such as an elbow, a union, or a large gate valve rim). It cannot slide over a bare piece of 63mm metric pipe. If you need to connect this adapter to a piece of raw metric pipe, you must first place a standard 63mm Straight Coupling onto the pipe line.
- Never Intermix Standard ABS Cements with this Rigid PVC Fitting. When cementing this adapter into place on high-flow manifolds or primary drain loops, always utilize a designated multi-purpose or PVC-specific solvent cement and clear primer loop. Never use standard black ABS transition glues or general hardware plumbing adhesives. Intermixing incompatible adhesive compounds will fail to break down the surface gloss of the rigid uPVC matrix, resulting in a weak chemical weld that can give way and leak under system pressure.
- Use a Strict 24-Hour Cure Timeline Before Launching High-Pressure Runs. Because 2-inch lines handle a massive volume of active fluid weight and can experience significant pressure during pump startup, always let your solvent joints cure for a minimum of 24 full hours before firing up active loops. Letting the assembly sit allows the solvent chemicals to fully evaporate, locking the metric wall and the imperial adapter into a single, fused piece of plastic. Rushing water through a fresh joint can weaken the chemical bond, creating microscopic tracking paths that will slowly drip over time.
