Oil & Gas

Chesterton Customseal is the leading supplier of innovative sealing solutions for the Oil & Gas industry.

Proven Sealing Technology for the Toughest Conditions

In the oil and gas industry, equipment is pushed to extremes — and no component shoulders more pressure than the seal.

From extreme temperatures and crushing pressures to deeper drilling demands and relentless exposure to aggressive chemicals, seal performance is critical to equipment reliability, service life, and overall operational safety.

From packing and valve stem seals to other mission-critical components, quality and durability aren’t optional — they’re essential. Seals directly affect performance, maintenance intervals, and most importantly, the safety of everyone on site.

As a proud member of the Subsea Innovation Cluster Australia (SICA), Chesterton Customseal leverages decades of global expertise to deliver innovative sealing solutions engineered to thrive under the harshest oil and gas conditions.

Valve Seals, Packing Seals and Sealing Solutions for Oil & Gas Applications

Effective sealing starts with the right material and design.

Polymers like PTFE and PEEK deliver exceptional durability in extreme conditions — PTFE providing superior chemical resistance and high-temperature performance, and PEEK offering outstanding toughness and resistance to acids, organics, and bases.

Upstream

The exploration and recovery sector demands sealing solutions that guarantee excellent performance and longevity whilst recovering hydrocarbon reserves.

Midstream

When processing and transporting raw natural gas and crude oil, advanced material and design seals are essential to prevent leaks, conform to legislation and – crucially –continue to do this for extended periods under duress.

Downstream

Processing at plants and refineries is a 24/7 process that demands seals that offer excellent MTBF. This is vital to meet environmental responsibilities and cut maintenance tasks and unexpected shutdowns that dramatically affect the bottom line in this highly competitive industry.

Challenges Faced by the Oil & Gas Industry

Extreme Temperatures & Pressures

Seals must withstand harsh temperatures and high-pressure conditions without compromising performance.

Aggressive Chemicals

Corrosive hydrocarbons and drilling fluids require seals with superior chemical resistance to prevent degradation.

Rapid Gas Decompression (RGD)

Specialised designs are needed to handle sudden pressure drops and avoid seal failure.

Sour Gas (H₂S) Resistance

Seals must resist chemical attack and embrittlement in the presence of hydrogen sulfide while maintaining leak-tight performance.
