Flanged Spool Piece
Product Overview
Let's cut to the chase: If you're installing fire hydrants in the Philippines, you need a flanged spool piece that works as hard as you do on the job site. That's exactly what the KeyLion® ductile iron flanged spool piece is built for.
We designed this fitting from the ground up for Philippine conditions. It connects underground water supply lines to outdoor fire hydrants, and lets you adjust the hydrant's height right on site-no custom cutting, no extra modifications, no wasted time. Every unit is factory-tested to meet Philippine BFP (Bureau of Fire Protection) standards, so you can trust it for municipal projects, commercial buildings, and residential developments across Luzon, Visayas, and Mindanao.
Crafted from heavy-duty ductile iron and finished with a thick yellow epoxy coating, it's made to withstand the country's harsh climate: the humidity of Manila, the salt spray of Cebu, and the extreme heat of Davao. The smooth, straight internal bore ensures unobstructed water flow, while the corrosion-resistant coating guarantees long-term durability for both above-ground and buried installations. We've had these units in service for 5+ years in coastal areas with zero rust issues, so you know it's built to last.We've been supplying these fittings to Philippine contractors for over 5 years, so we know exactly what works on local job sites.
Key Features
■ 100% Identical Double Flanges
Same size and bolt pattern on both ends - no alignment headaches during installation. Installers can quickly match it with standard fire hydrant bases and pipeline flanges, cutting down on on-site fitting time by up to 40%.
■ Heavy-Duty Ductile Iron Construction
Made from high-grade ductile iron, it resists mechanical damage and pressure surges common in Philippine construction sites. Built to last for decades, it's the go-to choice for long-term fire protection projects.
■ Superior Corrosion Protection
Thick, industrial-grade yellow epoxy coating covers every surface. This coating is resistant to rust, salt spray, and environmental damage - perfect for outdoor installations in cities like Manila, Cebu, and Davao.
■ Unobstructed Water Flow
Smooth straight-bore design ensures full, consistent water flow to the hydrant. No blockages, no flow restrictions - critical for ensuring the hydrant performs at peak capacity during fire emergencies.

Pre-Installation Check
Clean the flange surfaces thoroughly with a wire brush to remove dirt, dust, or oil. Ensure no debris is left on the sealing surface - even small particles can cause leaks later. This step is critical for complying with local fire safety installation codes.
Gasket Placement
Place a high-quality rubber gasket between the spool piece and connecting flanges. Use a gasket that matches the flange size (DN100/DN150) to ensure a tight, leak-proof seal.
Bolt Tightening
Align the bolt holes and tighten the bolts evenly in a cross pattern (e.g., top-bottom, left-right) to avoid flange deformation. Tighten to the recommended torque (per ANSI/ASME B16.5 standards) for a secure fit.
Leak Test
After installation, conduct a pressure test to check for leaks. Slowly increase the pressure to the rated level (PN10/PN16) - if no leaks are detected, the installation is complete. This test is mandatory for all Philippine fire protection system installations.
Maintenance& Long-Term Care
Designed for minimal upkeep, this spool piece reduces maintenance costs for Philippine fire system owners. Here's our recommended care routine, based on years of field experience:
Regular Bolt Inspection
Check flange bolts quarterly to ensure they're tight. Vibration and temperature changes can cause bolts to loosen over time - tightening them prevents leaks and flange damage, which is a common issue we see in local projects.
Coating Maintenance
If the epoxy coating is chipped or scratched from external damage, clean the area thoroughly and apply a touch-up coat of epoxy paint. This simple step stops rust from forming and extends the spool piece's lifespan for years.
Hydrant Replacement
When replacing a fire hydrant downstream, simply unbolt the spool piece. There's no need to excavate the main water line or shut down the entire water system. This design makes on-site maintenance much more flexible and efficient, saving labor costs and reducing project downtime compared to traditional fittings
No Regular Internal Cleaning Needed
Thanks to the straight-through design, dirt and debris can't build up inside the spool piece. Water flows smoothly without blockages, so there's no need for regular internal cleaning or flushing.

Questions We Get From Local Contractors
Q1 What is a flanged spool piece used for in Philippine fire systems?
A: Let's be real-this is the unsung hero of any fire hydrant installation. It's the critical link between underground water mains and outdoor hydrants, and it lets you adjust the hydrant's height right on site to fit your project's layout. Whether you're working on a municipal line, a commercial building, or a residential subdivision in Luzon, Visayas, or Mindanao, this fitting makes the whole process way smoother.
Q2: Are both flanges the same size?
A: 100% identical, every single time. Same size, same bolt pattern, no exceptions. We designed it this way specifically to eliminate the alignment headaches that slow installers down on tight job sites. No more measuring, no more custom fitting-just line up the holes, bolt it down, and move on.
Q3: Can this spool piece be used for buried installation?
A: Absolutely. The thick yellow epoxy coating we use gives it top-tier corrosion resistance, so it works perfectly for both above-ground and buried underground use. We've installed hundreds of these units in coastal areas with high moisture, and we've never had a rust issue.
Q4: Do I have to clean the inside of it on a regular basis?
A: Nope, no regular cleaning needed at all. The straight-through design keeps dirt and debris from building up, so water flows smooth and steady without any extra work. That's one less thing your team has to worry about during maintenance checks.
