• This product is a precision-machined brass replacement ball joint designed to upgrade and reinforce the original ball joints found in commercially available plastic model kits.
• Please measure the diameter of the ball portion of your existing joint and select the corresponding size. (Insert photo showing measurement with calipers.)
• This product is primarily intended for use with sockets molded in polycaps (polyethylene / PE).
• If the socket is molded in PS or KPS plastic, there is a risk of damage. Repeated movement may cause wear, leading to loosening or cracking of the socket.
• The ball portion of this product is made from hard brass. Even when used with polycaps (PE), repeated insertion and removal may cause damage. Please minimize removal and reinstallation.
• If the joint feels loose after insertion, apply a very small amount of commercially available instant adhesive to the ball surface and allow it to cure to adjust the fit.
• If the fit is too tight, do not force assembly. Doing so may damage the socket component. If painting is desired, apply a commercially available metal primer beforehand. Please note that paint thickness may affect the fit.
• Do not paint the plastic kit while this product is inserted. Doing so may cause solvent crack or chemical crack in the plastic parts.
• Specifications are subject to change without prior notice.
