General purpose
Technical Overview:
Carlock Sealing Tech provides high-precision CNC machined static seals, including O-Rings and X-Rings (Quad-Rings). Our machined approach is engineered specifically for applications where standard molded parts fail due to dimensional constraints or chemical incompatibility. By utilizing a No-Tooling manufacturing process, we deliver custom static seals in any diameter (up to 2000mm+) with rapid turnaround times.
Core Materials for Machined Static Seals:
The performance of Carlock’s static seals is driven by our selection of premium semi-finished polymers:
HPU (Hydrolysis-resistant Polyurethane): Ideal for high-pressure hydraulic applications requiring superior extrusion resistance and mechanical strength.
Modified PTFE: Offers near-universal chemical resistance and thermal stability for aggressive industrial environments.
FKM (Viton™) & NBR: Tailored for specific oil, fuel, and temperature requirements, machined to exacting tolerances.
Machined vs. Molded Advantage:
Our machined O-rings and X-rings feature superior edge definition and flash-free sealing surfaces. This allows for optimized compression ratios and the ability to customize cross-sections to compensate for non-standard groove dimensions or worn hardware.
Brand Compatibility & Interchangeability:
Carlock profiles are high-performance, functional alternatives to leading global brands, including:
SKF / Economos (SealJet material profiles)
Trelleborg Sealing Solutions
Parker Hannifin
Technical Disclaimer:
Seal selection should be verified based on fluid media, temperature, and pressure requirements.

Q1: What are the advantages of machined O-rings compared to molded ones?
A: Machined O-rings offer two primary advantages: customization and material quality. CNC machining allows for any custom diameter and cross-section without tooling costs, ideal for non-standard housings. Furthermore, machined seals are cut from high-grade semi-finished tubes (like HPU or Modified PTFE), which often possess superior mechanical properties compared to standard commercial molded rubber.
Q2: Can Carlock machine O-rings and X-rings from high-performance materials?
A: Yes. We specialize in machining static seals from a wide range of advanced polymers, including Hydrolysis-resistant Polyurethane (HPU), Modified PTFE (Teflon™), FKM (Viton™), and high-spec NBR. This ensures our seals can withstand extreme temperatures, aggressive chemicals, and high-pressure environments where standard materials fail.
Q3: Are your machined seals interchangeable with brands like SKF or Trelleborg?
A: Absolutely. Our CNC technology allows us to precisely replicate or optimize profiles from leading manufacturers such as SKF (SealJet/Economos), Trelleborg, and Parker. We provide functionally equivalent or superior alternatives with significantly shorter lead times.
Q4: What is the maximum size for a machined static seal?
A: At Carlock Sealing Tech, our CNC capabilities allow us to produce seamless machined O-rings and static seals in diameters ranging from 5mm to over 2000mm.
