Shop Superlok SR Stainless Tube Stub Reducer
Our Superlok Series SR fractional and metric tube stub reducers, crafted from high-quality 316 stainless steel, are designed to seamlessly connect different sized tubing within hydraulic and fluid power systems. These reducer fittings allow for the adaptation of smaller or larger tubing to corresponding tube fittings, enabling a smooth transition between varying tubing sizes. The tube stub side mimics a piece of tubing, which is then inserted into another tube fitting for a secure connection. These fittings are commonly used in industries such as analytical and gas measurement equipment, particularly in OEM equipment production, offering a reliable and efficient solution for tubing size transitions. Superlok's tube stub reducers provide exceptional flexibility and performance in a wide range of applications.
