Aerolite Cross-Reference to Klingersil, Lamons, Tombo, Valqua and Flexitallic Grades

Which Aerolite^® grade to ask for when your specification names another maker's gasket material. Compared on construction, with the datasheets linked so you can check.

Most gasket specifications are written around one manufacturer's grade names. This page lists the Aerolite^® grade that is built the same way as each of those grades, so a buyer or engineer can ask for the comparable Aerolite^® material and compare the two datasheets side by side. TBJ-UTEX manufactures every Aerolite^® product below in Johor Bahru, Malaysia.

What the tables mean. A grade is listed against another maker's grade when it shares the same material class and construction, or when both are made to the same dimensional standard. That is the whole claim. The tables do not say that two grades perform the same under pressure or temperature; those figures are on each product's datasheet, and your engineer should compare them for the service in question before substituting.

Compressed non-asbestos fibre sheet

Basis: Same fibre and binder class. All four Aerolite grades are made in the same sheet sizes with thickness tolerance to BS 7531. Grade details, sheet sizes and the cutting service are on the CNAF gasket page.

CNAF sheet	Aerolite^® NA3100	Aerolite^® NA3900	Aerolite^® NA3909	Aerolite^® NA4420
Construction	Organic fibre, NBR binder	Aramid and organic fibre, NBR binder	Aramid and organic fibre, NBR binder, steel wire reinforced	Aramid and glass fibre, NBR binder
Klingersil^®	—	C-4243 / C-4403 / C-4400	—	C-4430
Lamons^®	L420	L441	—	L443
Tombo^®	1995	1935	—	—
Valqua^®	6500	6500	6502	—

Listed for cross-reference only. Verify the datasheets side by side before substitution.

Flexible graphite sheet

Basis: Same reinforcement construction: homogeneous graphite, 316L tanged insert, or 316L foil insert. Grade details are on the graphite page.

Graphite sheet	Aerolite^® GS1004	Aerolite^® GS3004	Aerolite^® GS7004	Aerolite^® PSM-300
Construction	Homogeneous expanded graphite, no insert	Graphite with 0.1 mm 316L tanged insert	Graphite with 0.05 mm 316L foil insert	High-grade graphite with 0.1 mm 316L tanged insert
KLINGER^®	—	PSM	SLS	PSM
Lamons^®	LG-L	LG-TC	LG-SS	LG-TC
Tombo^®	1200	1210-A	1215-A	1210-A

Listed for cross-reference only. Verify the datasheets side by side before substitution.

Kammprofile gaskets

Basis: Same construction: a serrated metal core with a soft facing on each side. Pipe-flange sizes are to ASME B16.20; exchanger gaskets are made to the exchanger drawing. Styles, core alloys and facings are on the kammprofile page; exchanger details on the heat exchanger page.

Brand	Their product	Aerolite^® product
Flexitallic^®	Flexpro	Aerolite^® Kammprofile, styles KP1, KP2 and KP3
KLINGER^®	Maxiprofile	Aerolite^® Kammprofile, styles KP1, KP2 and KP3
Lamons^®	Kammpro	Aerolite^® Kammprofile, styles KP1, KP2 and KP3

Listed for cross-reference only. Verify the datasheets side by side before substitution.

Spiral wound and ring type joint gaskets

These are not cross-referenced by brand grade. Spiral wound gasket dimensions and ring type joint ring numbers are defined by ASME B16.20 and API 6A, not by any manufacturer, so a gasket from any maker carrying the same nominal size and class, or the same ring number, is made to the same dimensions. Ask for the Aerolite^® spiral wound gasket by size, class and winding material, or the ring type joint by ring number using the RTJ dimension chart.

PTFE sheet

Basis: Same filler type and the same intended service. Grades are compared on construction only. The full range is on the PTFE page.

Aerolite^® product	Brand	Their product	Construction compared
Silica-filled PTFE sheet	Garlock^®	Gylon 3500	Structured PTFE with silica filler for strong acids.
Aluminosilicate-filled PTFE sheet	Garlock^®	Gylon 3504	High-compressibility PTFE with microspheres for fragile and glass-lined flanges.
Expanded PTFE sheet and joint sealant	GORE, KLINGER^®	Expanded PTFE ranges	No single grade named; compared on construction as 100% expanded PTFE.

Listed for cross-reference only. Verify the datasheets side by side before substitution.

O-rings

Dash sizes are defined by AS568, JIS B 2401 and ISO 3601, not by any manufacturer, so an O-ring of the same dash size and compound family interchanges on dimensions. Aerolite^® O-rings in NBR, FKM, EPDM and silicone are supplied by dash size, and interchange on dimensions with Parker^®, KLINGER^® and TOMBO^® parts of the same dash size. Compound, hardness and temperature range must still be matched to the service.

Before you substitute

A cross-reference gets you to the right family of material. Whether a specific gasket can replace another is an engineering decision for the joint in question. Check these against both datasheets:

Media. Chemical compatibility of the binder, filler or elastomer with the process fluid.
Temperature. Continuous operating temperature and peak, not one or the other.
Pressure. Operating pressure together with temperature, using the pressure and temperature chart on the datasheet.
Flange. Flange type, surface finish and condition, and whether the joint is full-face or raised-face.
Bolt load. The seating stress the bolting can actually deliver against the gasket's m and y factors.
Certification. Any approval the line requires, such as fire-safe, FDA or TA-Luft, which is grade-specific and not transferred by a cross-reference.
