FRP/GRP 90 ELBOW

Optimize your piping layout with our precision-molded FRP 90 elbow. Designed to minimize friction loss, this GRP 90 degree elbow ensures smooth flow direction changes. Whether your site terminology refers to it as a FRP 90 bend or a GRP 90 degree bend, our fittings are manufactured for seamless integration. We stock the FRP 90 degree elbow (and the standard FRP 90° elbow) alongside GRP 90 elbow and GRP 90 bend options. These are essential FRP fitting and GRP fitting components for any compact piping system.

FRP/GRP 45 ELBOW

For gradual directional changes that reduce hydraulic shock, choose our FRP 45 elbow. This GRP 45 degree elbow is a critical GRP fitting for complex routing where space is limited. Often specified as a FRP 45 bend or GRP 45 degree bend, our components ensure structural continuity. The FRP 45 degree elbow (or FRP 45° elbow) provides a leak-free solution for diverting flow. We also supply GRP 45 elbow and GRP 45 bend variants to complete your FRP fitting list.

FRP/GRP EQUAL TEE

The FRP equal tee is the standard for splitting process flow into two identical streams. Engineered for high mechanical stress, this GRP equal tee is a fundamental FRP fitting for headers and distribution manifolds. Our FRP tee and GRP tee inventory is tested to ensure the branch connection is as strong as the main run, making it a reliable GRP fitting for all pressures.

FRP/GRP UNEQUAL TEE

Reduce installation time and costs with our FRP unequal tee, which eliminates the need for additional reducers at branch points. Also known as a FRP reducing tee or GRP reducing tee, this fitting is essential for stepping down line sizes efficiently. Our GRP unequal tee and FRP tee range is designed to handle the turbulence often associated with size transitions in a FRP fitting or GRP fitting system.

FRP/GRP CONCENTRIC REDUCER

Maintain perfect centerline alignment in vertical pipe runs with the FRP concentric reducer. As a vital FRP reducer, it ensures structural stability when changing diameters. Our GRP concentric reducer is built to match the specific pressure class of your piping system, ensuring a safe and durable GRP reducer installation. This FRP fitting and GRP fitting is key for standardizing flow rates.

FRP/GRP ECCENTRIC REDUCER

Designed specifically for pump suction lines, the FRP eccentric reducer features a flat side to prevent air pocket formation. This GRP eccentric reducer is critical for protecting pumps from cavitation. Our FRP reducer range ensures smooth transitions, and every GRP reducer we supply is dimensionally checked. Use this FRP fitting and GRP fitting for all horizontal pump connections.

FRP/GRP BLIND FLANGE

Securely terminate your lines or create access points with our FRP blind flange. Whether you need a temporary seal for hydro-testing or a permanent closure, our GRP blind flange delivers high-strength performance. Customers searching for FRP blindflange or GRP blindflange will find our products robust, lightweight, and easy to install within any FRP fitting or GRP fitting assembly.

FRP/GRP FULL FACE FLANGE

Our FRP full face flange is engineered for mating with flat-face valves and machinery. Adhering to strict FRP flange standard dimensions, this GRP full face flange ensures a complete seal across the gasket face. Sometimes referred to as a GRP s off flange, this heavy-duty flange FRP solution prevents bending moments during bolting. We are a leading supplier of FRP flange, GRP flange, and flange GRP connections.

FRP/GRP STUBEND FLANGE

Simplify bolt alignment during installation with our FRP stubend and backing ring system. This assembly, often called a FRP stubend with loose flange, allows the flange ring to rotate freely. We provide the complete FRP stub flange kit, including the GRP stubend (or GRP s on flange) and the GRP loose flange. Our FRP stub end and FRP loose flange combinations are the preferred FRP fitting and GRP fitting choice for field alignment.

FRP/GRP PUDDLE FLANGES

Prevent leakage in concrete water tanks and reservoirs with the SREX FRP puddle flange. Designed to be cast directly into concrete walls, this GRP puddle flange acts as a waterstop, ensuring a tight seal where pipes penetrate the structure. A specialized FRP fitting and GRP fitting for civil works.

FRP/GRP CROSS

For complex distribution grids requiring four-way flow, the FRP cross is the ideal solution. This specialized GRP fitting is reinforced to handle multi-directional loads. Our GRP cross minimizes the need for multiple tees, saving space and reducing joint count. It is a robust FRP fitting and FRP cross component for chemical headers.

FRP/GRP END CAP

Provide a permanent, lightweight closure to your pipe run with a FRP end cap. Unlike removable flanges, the FRP end cap molding is bonded directly to the pipe for maximum integrity. Our GRP end cap (or FRP endcap) is a cost-effective alternative for permanently dead-ending a line. Available as both a GRP fitting and FRP fitting, the GRP endcap ensures zero leakage.

FRP/GRP LAMINATION KIT

Ensure professional-grade field joints with our FRP lamination kit. Whether for GRP in situ lamination or emergency repairs, this kit contains all necessary GRP lamination materials. It is the industry standard for creating a seamless lamination joint for GRP pipe. We also supply specific lamination kit for GRE pipe and lamination kit for GRP pipes, making GRP pipe lamination straightforward and reliable on-site. Trust our FRP lamination and GRP lamination solutions for creating permanent bonds, including GRE pipe lamination.
