Premium quality internal coupling PVC furniture grade fittings available for sale online from PVC Pipe Supplies at low prices and bulk order wholesale discounts. Internal coupling furniture grade PVC fittings are used to join two pieces of pipe or fittings together without external couplers or solvent welding with primer and cement. They are designed to provide nearly seamless, sturdy and professional looking connections. Furniture grade PVC internal couplings are not intended for quick release structural designs. They are engineered to form reliable tight junctions with high tolerance and may require slight hammering to fully connect. This makes them difficult to remove once in place. Use internal couplers to create semi permanent joints between furniture PVC sections for projects, products, DIY crafts, garden structures and medical applications.
Available internal coupling PVC furniture grade fittings are made by leading manufacturer C&S Plastics® in the USA. C&S® furniture couplers are made from high quality materials, colors and ultraviolet (UV) blocking compounds. They are heavy duty and have nearly five times greater durability against impacts and shattering. They offer lasting resistance from sunlight damage that can cause PVC weakening (embrittlement) and discoloration. They are engineered to be long lasting and capable of harsh weather exposure. Internal couplings are not NSF rated to handle potable (drinking) water or pressurized fluid applications. They are FDA approved non toxic and safe, made without phthalates or heavy metals.
Internal coupling PVC furniture grade fittings come without any production markings, writings, barcodes or other labels. They have a glossy, smooth surface finish and leave only a small seam when installed for a clean, professional appearance. Internal couplings are schedule 40 furniture fittings for use with other schedule 40 piping. They come in 1 ¼” diameter size only. Available colors include white, black, gray, green, orange, purple, red, yellow and blue. Use solvent welding methods to form uniquely tight and strong connections.
Internal coupling furniture PVC fittings are used to join two furniture pipes or fittings together from the inside for a nearly seamless connection. They allow pipe parts in DIY projects to be connected without external couplers or solvent welding with primer and cement. Internal furniture couplers are designed to provide a sturdy and professional looking connection. Furniture grade PVC internal couplings are not intended for quick release structural designs. They are engineered to form a tight junction with high tolerance and may require slight force to fully connect. This makes the couplings resistant to removal once in place, creating reliable joints between furniture PVC sections in DIY projects. Internal furniture couplers are used to make smooth, sturdy, and professional structures that appear one piece. This hidden connector design improves overall visual design and structural strength. Furniture PVC couplings are useful for large designs with multiple pipe lengths as they allow disassembly for more compact knockdowns.
**Notice** Internal coupling PVC furniture fittings are not for use in pressurized liquid or pressurized air applications.
Internal Coupling PVC Furniture Fitting Sizes and Options
Internal coupling PVC furniture fittings come in 1 1/4” size. Color options include white, black, gray, red, blue, orange, green, yellow, and purple. The couplings have a tapered, internal socket to accommodate pipe variances and ensure a secure fit. Internal furniture couplings are suitable for removable push-to-fit and permanent solvent weld installation. Push-to-fit installation is nonpermanent and allows repeatable assembly and disassembly. Solvent weld installation is permanent and can be performed with PVC primer and cement.
Technical Specifications
Internal coupling PVC furniture fittings are made in the USA by C&S Plastics®, a trusted manufacturer with over 30 years experience in professional furniture PVC pipe work. The couplers are made from ultra strong, furniture grade PVC material with premium, high quality colors, and UV blocking compounds. This specially formulated PVC has heavy duty mechanical durability and is designed to withstand prolonged exposure to sunlight without degrading. The couplings are certified safe, nontoxic, and free of heavy metals and chemicals such as lead and phthalates. Furniture couplings are not NSF 61 approved for potable water applications.

Applications and Uses
Internal couplings can be used in furniture PVC pipe projects to join pipe lengths and fittings together. Their unique design creates hidden joints that ensure smooth surfaces, clean lines, and a polished finish that reduces buildup of dirt and grime for less maintenance and lowers the risk of accidents from snags. Their internal placement also improves the stability and balance of a furniture pipe structure by reinforcing joints. Internal couplings are used in furniture pipe DIY builds by hobbyists, students, professionals, and in commercial applications. Example uses include building furniture, roofs, sloped structures, base supports, garden items, recreation equipment, small animal and dog training items, retail displays, photography backdrops, exhibition stands, banner frames, flag poles, and temporary structures such as event booths.
Our internal coupling PVC furniture fittings are made in the USA and engineered for quality and strength to provide a superior, long lasting solution for creative DIY applications. Their professional manufacturing using premium materials and color holds up against weather, impacts, and sunlight with low effect on strength or color.
