GRUVLOK

GRUVLOK grooved pipe couplings are available with different pressure ratings depending on size and model. For example, the 14-inch coupling (SKU 60XP12) is rated for 300 psi at 150°F, while the 6-inch coupling (SKU 408HF6) is rated for 1,000 psi. The 8-inch and 10-inch couplings (SKUs 408HF5 and 408JM0) are rated for 800 psi. These ratings are based on the coupling design, material, and seal. Always verify the specific pressure rating for your application and pipe size. The ratings are maximum operating pressures and should not be exceeded. For detailed specifications, refer to the product datasheets or contact 3G Electric.

GRUVLOK grooved pipe fittings and couplings are typically made from ductile iron, specifically A536 65-45-12 grade. The housings are often painted for corrosion resistance. Seals are commonly EPDM, suitable for water and various industrial fluids. Some fittings, like the concentric reducer elbow (SKU 408GX7), may have different materials or coatings. The ductile iron construction provides strength and durability. Standards such as ASTM A536 and ASTM A153 apply. For specific material requirements, check the product specifications. 3G Electric can provide material certificates upon request.

GRUVLOK grooved pipe couplings are available in a range of sizes to accommodate different pipe diameters. Common sizes include 2 inches, 6 inches, 8 inches, 10 inches, 12 inches, and 14 inches. For example, the 2-inch x 1-1/4-inch concentric reducer elbow (SKU 408GX7) is used for size transitions. Couplings are sized to match the pipe outer diameter. The size is typically indicated in the product description, such as 14 in x 14 in for SKU 60XP12. Ensure the coupling size matches your pipe size and groove specifications. 3G Electric stocks various sizes and can source additional sizes as needed.

GRUVLOK products meet various industry standards and hold approvals from recognized organizations. These include ASTM A536 for ductile iron castings, ASTM A153 for zinc coating, ASTM A53 for pipe, ASTM A563 for nuts, ASTM D2000 for rubber products, and SAE J429 for bolts. Approvals may include cULus Listed, FM Approved, IAPMO UPC, LPCB, NSF 61, and VDS. Not all products carry every approval; check individual product specifications. These standards and approvals ensure the products meet requirements for fire protection, plumbing, and industrial applications. 3G Electric can provide documentation for compliance verification.

GRUVLOK offers both rigid and flexible grooved pipe couplings. Rigid couplings, such as the clamp coupling (SKU 60XP12), provide a rigid joint that resists angular and linear movement. Flexible couplings, like the flex bolted coupling (SKU 408JM0), allow for some movement to accommodate thermal expansion, contraction, and minor misalignment. The choice depends on the piping system requirements. Rigid couplings are often used where pipe movement is not desired, while flexible couplings are used in systems subject to vibration or temperature changes. Both types are available in various sizes and pressure ratings. Consult the product specifications for specific performance characteristics.
