V-packings and Chevron Stacks

V-packings and Chevron Stacks for Oil & Gas industry

M Barnwell Services’ selection of V-packings and Chevron Stacks are used in fulfilment and creation equipment within the Oil & Gas industry. They significantly decrease the hazard of hidden gaps, flow lines, and inlet expansions. This leads to an increase product life and reduced machine downtime.

V-packings and Chevron Stacks can withstand temperatures of between -41°C and +225°C, and pressure of up to 40,000 PSI and beyond depending on an application.

M Barnwell Services also design and produce custom-made chevron stacks for specific installations, where extreme bi-directional stress, in hostile environments, demands persistent sealing.

V-packings and Chevron Stacks

V-packings are precision moulded rubber or mixture rubber/fabric sealing solutions developed to guard devices against leakage and costly downtime. The multi-lip structure automatically reacts to variations in system pressure. M Barnwell Services’ Vee packing (V-packing), or Chevron Stack kits contain one or more rings with a V-shaped profile. They are situated amongst male and female adapters fitted at the top and bottom, therefore they improve execution and prevent extrusion. Furthermore, this makes a multi-lip packing adequate for mechanically demanding environments in rod and piston applications. V-packings are designed for use in rods & pistons, presses, plungers & rams, and other hydraulic installations. They are obtainable in a selection of rubber and fabric compositions subject to installation demands.

E & OE.


We offer V-packing kits produced from our selection of high-performance elastomer materials, including Nitrile (NBR), Hydrogenated Nitrile (HNBR), Fluorocarbon (FKM) and PTFE, PEEK.

Other high-temperature and high-pressure materials are also available on request.


Many sizes available with short lead times.

Custom made design service for specific applications also available.

Chevron Stack Kit Applications

General installations include mud pump packing, where the seals face high stress and an abrasive media comprising of diverse oils, solids, and water. However, for higher stress installations, additional V rings can be fixed to the stack as needed.
