SEELYE

SEELYE is a manufacturer of thermoplastic welding consumables and accessories, supplying rods, tips, and related equipment for the fabrication and repair of plastic structures. The brand is recognized in industrial maintenance, marine fabrication, and chemical processing sectors for its range of welding rods compatible with common thermoplastics including PVC (Type 1), HDPE (including marine-grade), LDPE, PP, and ABS. SEELYE products are designed for use with standard hot-air or speed welding tools, enabling operators to perform fusion welding on plastic tanks, pipes, liners, and ductwork. The product line includes round and triangular rod profiles in diameters from 1/8 in to 3/16 in, supplied in 48 in lengths, typically packaged in 1 lb bundles with rod counts varying by diameter and material. SEELYE also offers speed welding tips, such as the #10A round tip for 3/16 in maximum rod diameter, which are compatible with common welding gun configurations. These tips facilitate higher deposition rates compared to standard tack welding tips. The rods are manufactured to dimensional tolerances suitable for manual and automated welding processes, with color options including white, black, gray, clear, and off-white to match base materials or provide visual contrast for weld inspection. Marine-grade HDPE rods are formulated for UV resistance and weatherability, making them appropriate for dock fenders, boat components, and outdoor storage tanks. PVC Type 1 rods meet the requirements for welding rigid PVC sheets and fittings in ventilation and chemical handling systems. 3G Electric stocks SEELYE welding rods and tips for global distribution, supporting maintenance and fabrication operations that require consistent material properties and reliable weld integrity. The product range covers common thermoplastic welding needs without requiring specialized storage or handling beyond standard dry conditions. SEELYE consumables are suitable for use in shop environments and field repairs where portable welding equipment is deployed.

Frequently asked questions

Common questions about SEELYE from 3G Electric.

What materials are SEELYE thermoplastic welding rods available in?

SEELYE offers welding rods in PVC Type 1, HDPE (including marine-grade), LDPE, PP, and ABS. Each material is formulated to match the chemical resistance and mechanical properties of the corresponding base sheet or pipe. PVC rods are available in round and triangular profiles; HDPE rods are supplied in round profile with marine-grade options for enhanced UV stability.

What diameters and lengths do SEELYE welding rods come in?

SEELYE welding rods are typically supplied in 48 in lengths. Common diameters include 1/8 in, 5/32 in, and 3/16 in. Rod count per 1 lb package varies by diameter and material—for example, 1/8 in PVC round rods yield approximately 23 rods per pound, while 5/32 in HDPE rods yield about 33 rods per pound. Exact counts are listed on individual product specifications.

Are SEELYE speed welding tips compatible with standard hot-air welding guns?

Yes, SEELYE speed welding tips, such as the #10A round tip for 3/16 in maximum rod diameter, are designed to fit standard hot-air welding guns used for thermoplastic fabrication. These tips allow for continuous rod feed and higher deposition rates compared to tack welding tips. Always verify the tip shank diameter and thread type against your welding gun specifications.

What is the difference between marine-grade HDPE rods and standard HDPE rods from SEELYE?

Marine-grade HDPE rods from SEELYE are formulated with UV stabilizers and additives to resist degradation from prolonged sun exposure and saltwater environments. Standard HDPE rods are suitable for indoor or sheltered applications. Both are round profile and available in 5/32 in x 48 in dimensions, but marine-grade is recommended for docks, boat components, and outdoor tanks.

Can SEELYE PVC welding rods be used for both Type 1 and Type 2 PVC?

SEELYE PVC welding rods are specified as Type 1, which corresponds to rigid PVC (PVC-U) with a cell classification per ASTM D1784. These rods are intended for welding Type 1 PVC sheets and fittings. For Type 2 PVC (high-impact), verify compatibility with the base material's formulation, as impact modifiers may affect weld strength. Consult the manufacturer's guidelines for specific applications.
