Control Water JetThe ISOTEK sealing and isolation product line is manufactured out of the Lamons Denver facility. This is a dedicated 17,000 sq. ft. facility, completely designed for the ISOTEK products.  All products are manufactured in the U.S.A to ISO 9001:2015 standards. Real time production boards are utilized throughout the entire manufacturing process. A paperless production floor allows for streamlined production and assures quality and accurate dimensions which are critical for sealing performance.

ISOGUARD™ Sealing/Isolation Gaskets

NSF logoThe ISOGUARD™ sealing/isolating gasket system is designed for general applications where electrical flange isolation and corrosion control are required on pipes containing water/wastewater, gas, natural gas, oil and other hydrocarbon based medias up to 302ºF (150ºC). Available for flat face, raised face and ring type joint flanges. The ISOGUARD sealing/isolating gasket system consists of a retainer with an incline-plane seal groove designed to optimize each seal’s elastic memory, in conjunction with a proven rectangular sealing element (“Quad” ring). This design guarantees low bolt load requirements and high sealing reliability.

 

ISOGUARD General Offering
Gasket Type Retainers Seal Elements Pressure Class
E and F G10, G11, G7, Phenolic PTFE, Nitrile, Viton, EPDM ANSI(150#-1500#, API (2-5K), PN (20-250)

isoGuardscreenThe DEFENDER Tandem Sealing/Isolation Gaskets utilizes a Tandem Seal Configuration (two seals per gasket face) for subsea and API 10K applications. The backup Viton O-ring Seals are bidirectional and can thus stop external pressure from the sea water while the Spring-Energized PTFE main seal stops the internal pipe pressure.

DEFENDER™ Sealing/Isolation Gaskets

The DEFENDER™ sealing/isolating gasket system is designed for critical/extreme applications. Manufactured with a 316 stainless steel core retainer and laminated on both sides with high strength laminates, the DEFENDER gasket is resistant to deforming under load and is used when electrical isolation and corrosion control are required on pipes containing gas, natural gas, oil and other hydrocarbon based medias up to 392ºF (200ºC). Available for flat face, raised face and ring type joint flanges from 1/2” to 60” (including corresponding API and DN diameters), ANSI 150-2500#, API 2-10K and PN20-PN420, the DEFENDER gasket is an engineered solution for trouble-free operation that eliminates costly leaks and provides a solution for fugitive emissions.

DEFENDER FS™ Sealing/Isolation Gaskets (Fire Safe)

The DEFENDER FS™ sealing/isolating gasket is designed to withstand the rigorous API standard 6FB (Third Edition) test and therefore provides a solution for those who want to electrically isolate their flange while also requiring protection against the introduction of fire in and around the flange. The objective of the test is to monitor the total leakage for the duration of the burn/cool-down cycle and during re-pressurization. Leakage was determined by the total water level drop through a visual sight gauge during the burn/cool-down cycles, by manually catching the water in a calibrated container during re-pressurization.  The results concluded that the Defender FS Gasket was able to maintain its fire safe characteristics throughout the entirety of the test. During the 30 minute burn and 30 minute cool down period, the measured leakage was 0 ml/min versus the allowable rate of 22.765 ml/min. The leakage rate during the re-pressurization cycle was 5 ml/min versus the allowable rate of 22.765 ml/min. Based on years of technological experience, the DEFENDER FS sealing/isolating gasket not only meets but exceeds the pressure-containing capabilities in standard 6FB (Third Edition) as outlined by API.

Matrix CPG®

NSF logoMatrix CPG® is a superior performance biaxially orientated PTFE gasket material with a unique Corrugation Profile. The material has been specially formulated to accept this corrugated effect. Engineered to achieve low leakage at minimal load. The high and low density points across the sealing area allow varying loads to be applied radially but achieve a consistently low leak rate. Ideal for glass lined, plastic and FRP flanges where high gasket stress are not possible.

Sleeve and Washer Sets

alignFlangesLamons sleeve and washers sets, when combined with our sealing/isolation gaskets, complete a Flange Isolation Kit. For a successful flange isolation kit, it’s critical to use the appropriate material for your application. Compressive strength, flexural strength, and cut through resistance are key material physical properties that should not be over looked.

cutThrough

Cut-Through Resistance
Cut Through Resistance and Flexural Strength is critical in selecting sleeve material for your flange isolation kit application. As nominal pipe size increases, as well as ANSI or API class, the fasteners (bolts/studs) increase in size and torque is generally higher. Larger and heavier stud bolts with higher torque loads can more easily cut through material during installation. This is more likely to occur if flanges and bolt holes are not in perfect alignment. Use or specify G10 sleeve material as a standard for all applications. Or consider G10 sleeves for applications of Nominal Pipe Size 12” and larger and ANSI pressure class 600# and higher.
