Repair and maintain your compatible patio swivel chair with this 2 pack of black swivel chair seat post bushings. These replacement bushings are designed for outdoor patio swivel chairs that use a 1" outside diameter seat post and a 1 5/8" inside diameter base pole. If your patio chair feels loose at the swivel connection, has a worn seat post insert, or is missing the original plastic bushing between the seat post and base, this replacement part can help restore the fit between those two chair components. Each bushing measures approximately 1 5/8" x 4 1/8", making it a practical patio chair replacement part for compatible swivel chair bases, outdoor furniture repair projects, and patio swivel chair maintenance. This black swivel chair seat post bushing is made for the connection point where the chair seat post fits into the base pole. On many patio swivel chairs, the bushing acts as the insert between the upper seat post and the lower base tube. Over time, the original bushing may wear down, crack, loosen, or become damaged from regular use, weather exposure, movement, and seasonal outdoor furniture storage. Replacing the worn bushing can help create a better fit between the chair seat post and base pole, making this part a useful solution for patio swivel chair repair, swivel chair bushing replacement, outdoor swivel chair bushing replacement, and patio furniture replacement parts. This listing includes four black replacement bushings, giving you a convenient 4 pack for repairing multiple patio swivel chairs or keeping extra bushings on hand for future outdoor furniture maintenance. The 4 pack is ideal for patio dining sets, outdoor swivel chairs, patio swivel rocker chairs, bar-height swivel patio chairs, and other compatible chairs that use this specific bushing size. Before ordering, always measure your existing chair parts carefully. This bushing is designed to fit into a 1 5/8" inside diameter base pole, and a 1" outside diameter seat post should fit into the bushing. Because patio furniture parts can vary by manufacturer, model, and year, confirming your measurements before purchase is the best way to make sure this swivel chair seat post bushing is the correct replacement part for your chair. The bushing measures approximately 4 1/8" long and is designed with a cylindrical shape, black plastic construction, and flange-style rings that help it seat inside the base pole. The top of the bushing is made to accept the seat post, while the outside of the bushing fits into the base tube. This design makes it useful as a plastic bushing, plastic insert, chair post bushing, patio chair bushing, swivel bushing, chair base bushing, and seat post bushing for compatible outdoor swivel chairs. It is not intended to be a universal chair part for every patio chair, so buyers should compare the dimensions to their existing bushing or chair base before ordering. Installation is straightforward, but the order matters. Always insert the bushing into the base pole before inserting the seat post into the bushing. The bushing should fit tightly into the base pole. A tight press-fit is normal and helps keep the bushing secure once installed. Do not force the seat post into the bushing before the bushing is installed in the base pole. For best results, clean the inside of the base pole before installation and remove any old broken plastic, dirt, rust flakes, or debris that may prevent the new bushing from seating properly. Once the bushing is pressed into place, the 1" outside diameter seat post can be inserted into the bushing. This replacement bushing is a smart option for customers searching for patio chair parts, outdoor chair parts replacement, patio swivel chair replacement parts, chair base replacement parts, swivel chair parts, swivel patio chair replacement bushings, patio chair replacement swivel parts, or outdoor furniture repair parts. Instead of replacing the entire patio chair, this small replacement insert may help address the worn connection area between the seat post and base pole when the chair uses the correct size. Many patio swivel chairs rely on small plastic bushings to reduce looseness and support the fit between metal components. When that original insert wears out, the chair may feel less secure, noisy, or uneven at the swivel connection. Replacing the bushing is often a simple first step in patio chair repair. These black bushings are also useful for maintenance crews, patio furniture repair shops, property managers, restaurants with outdoor seating, and homeowners who need to repair several compatible patio swivel chairs at once. Because this is a 4 pack, you can service multiple chairs from the same patio set or keep extras available for future repairs. Outdoor furniture parts are often easier to replace before the original part is completely damaged, so having additional seat post bushings on hand can make seasonal patio furniture maintenance easier. Use them for compatible patio swivel chairs, outdoor swivel chair parts, swivel rocker patio chair parts, chair swivel replacement projects, patio chair repair projects, and outdoor furniture replacement hardware needs. The black color is designed to blend naturally with many dark patio chair frames and base assemblies. Since the part is installed at the lower seat post and base connection, it is usually not highly visible once the chair is assembled, but the black finish gives it a clean replacement look. This makes it suitable for black, bronze, dark gray, and other dark metal patio chair frames where a black plastic insert is preferred. The smooth plastic construction also makes it a practical choice for a replacement bushing where metal-to-metal contact is not desired between the chair seat post and base pole. Before purchasing, check three important measurements. First, measure the inside diameter of the base pole where the bushing will be inserted. It should be 1 5/8" inside diameter. Second, measure the outside diameter of the seat post that fits into the bushing. It should be 1" outside diameter. Third, compare the length of your old bushing, if available, to the 4 1/8" length of this replacement bushing. If your measurements are different, this may not be the correct patio chair bushing for your furniture. Measuring first helps avoid ordering the wrong swivel chair replacement part. This swivel chair seat post bushing is not a complete chair base, not a swivel plate, not a metal seat post, and not a full patio chair repair kit. It is the black plastic replacement bushing only. It is intended for compatible patio swivel chairs that use this style and size of bushing at the seat post and base pole connection. If you are repairing a patio chair that has additional damaged parts, such as a broken metal base, bent seat post, damaged swivel plate, cracked frame, or missing hardware, those parts may need to be replaced separately. Use this 4 pack of black swivel chair seat post bushings to help maintain compatible patio swivel chairs and outdoor furniture. With the correct fit, these replacement bushings are a practical solution for patio chair bushing replacement, swivel chair repair, patio furniture repair, outdoor swivel chair repair, chair base repair, and seat post insert replacement. Whether you are fixing one chair or servicing a full patio dining set, these bushings provide a clean, simple replacement option for worn or missing seat post bushings. For best results, compare your chair's measurements to the product dimensions before ordering: 1 5/8" x 4 1/8" bushing size, fits a 1 5/8" inside diameter base pole, and accepts a 1" outside diameter seat post. Proper fitment is important. When the dimensions match, this black plastic swivel chair bushing can be a helpful replacement part for keeping compatible outdoor swivel chairs, patio swivel chairs, swivel rocker chairs, and patio furniture repair projects moving forward.
