Round Pull Tab Plugs
Cylindrical pull tab plugs are specialist protective components designed to seal and safeguard internal bores within fuel lines, fluid systems, and hydraulic assemblies. Also known as centre pull tab plugs or internal bore plugs, these versatile sealing solutions offer reliable contamination protection during transit, storage, and assembly processes across the UK's automotive, manufacturing, and engineering sectors. With their elongated cylindrical body and integrated pull tab featuring a finger ridge, these plugs provide both secure fitment and effortless removal, even when wearing gloves. Available in eco-friendly recycled LDPE and bio-LDPE materials, Vital Parts' cylindrical pull tab plugs combine environmental responsibility with exceptional performance, catering to internal diameters ranging from 17.5mm to 52mm. The rigid internal closure created by the extended length of these plugs ensures they remain firmly in place throughout handling, preventing dust, moisture, dirt, and contaminants from compromising sensitive O-rings and internal components within fluid-carrying systems.
