HAM-LET
Frequently asked questions
Common questions about HAM-LET from 3G Electric.
What is the pressure rating of HAM-LET single-valve manifolds?
HAM-LET single-valve manifolds, such as the M-01-4N-SS series, are rated to 10,000 psi (690 bar) for compatible configurations. The rating depends on the specific model, body material, and end connection. The M-01-4N-SS features a 1/4 in MNPT inlet and a 3 mm drain hole, constructed from 316L stainless steel. For applications above 10,000 psi, HAM-LET offers high-pressure needle valves and manifolds in additional series. Always verify the pressure-temperature rating for the exact model and operating conditions before installation.
Are HAM-LET Let-Lok fittings interchangeable with other double-ferrule fittings?
HAM-LET Let-Lok double-ferrule fittings are designed to be interchangeable with other major double-ferrule compression fitting systems, including Swagelok. This means the tube preparation, ferrule set, and installation procedure follow the same two-ferrule mechanical grip principle. Interchangeability applies to the fitting interface and tube connection, not to mixing components from different manufacturers within a single connection. For critical applications, specify HAM-LET ferrules and nuts together with HAM-LET bodies to maintain the intended performance and warranty coverage.
What materials are HAM-LET needle valves and fittings available in?
HAM-LET needle valves and compression fittings are commonly supplied in 316 and 316L stainless steel. Additional material options include brass, alloy 400 (Monel), alloy C-276 (Hastelloy), alloy 625, titanium, and various fluoropolymer seals and seats. Material availability varies by product family and size. For corrosive or high-purity applications, specify the required material and seal combination when requesting a quote. 3G Electric lists material specifications for each SKU in the product data.
What is the HAM-LET anti-tamper key used for?
The HAM-LET anti-tamper key, such as part number M-06-KEY-5MM-SS, is a stainless steel accessory used to operate or secure compatible HAM-LET valves. It prevents unauthorized adjustment of valve settings in industrial fluid and gas systems. The key is compatible with specific valve models, including the M-20M-80-8N-SS-V-LDI-KEY. It is typically used in applications where valve settings must remain fixed, such as sampling systems, analytical instrumentation, and process control loops. The key is a replacement part and should be matched to the valve model number for correct fit.
What tube sizes and end connections are available in HAM-LET compression fittings?
HAM-LET double-ferrule compression fittings are available for tube outer diameters from 1/16 in to 1 in and 2 mm to 25 mm. End connections include tube x tube, tube x MNPT, tube x FNPT, tube x MBSPP, tube x FBSPP, and tube x SAE threads. Configurations include straight unions, bulkhead adapters, 90-degree elbows, 45-degree elbows, tees, crosses, and reducers. Hex sizes and body dimensions vary by tube size and configuration. The Let-Lok series covers the majority of instrumentation tube fitting requirements.
Does 3G Electric provide HAM-LET product documentation for specification?
3G Electric provides manufacturer part numbers, material specifications, pressure ratings, and connection details for each HAM-LET SKU listed in its catalog. For detailed dimensional drawings, pressure-temperature curves, and material certificates, buyers can request documentation with a quote. HAM-LET publishes technical datasheets for its product families, and 3G Electric can supply these documents to support engineering review and procurement. Contact 3G Electric with the specific model numbers required for a documentation package.
