LET-LOK® Compression Tube Fittings

LET-LOK® tube fittings have been carefully manufactured to withstand the persistent demands for high-performance fluid system. Each one has passed a stringent tolerance test for high pressure, impulse, vibration, vacuum and temperature.

These precision-machined fittings are manufactured to exacting standards, employing the most state-of-the-art computerized automation.

All LET-LOK® fittings are backed by HAM-LET's commitment to the highest quality-control standards and skilled craftsmanship.

The LET-LOK® tube fitting was designed for applications were high reliability and quality is required. Customized for use in various instrumentation processes in industries such as chemical, petroleum, power generation and more.

Key features

Let-Lok® design creates a tight metal to metal sealing, thus allowing to hold pressure more then 4XMAWP (validated by burst testing) at a wide range of temperatures, same for high number of temperature cycles and make-remake cycles.

Manufactured to the highest standards, products undergo helium leak tests to meet industry highest standards.

Various configurations are available: straight, elbow, angled, tee, cross, plugs, caps, unions and various couplings.

End connections include NPT, ISO, BSPP, BSPT, SAE/ME.

Sizes available both in inch (1/16” to 2”) and mm (2 – 50 mm).

Quick and easy installation, does not require special tools.

Materials:

Standard straight fittings: SS 316L in accordance with ASTM A479, ASTM A276 and DIN EN10272.
Standard steel shaped fittings: SS 316L in accordance with ASTM A182 and DIN EN10122-5.
Heat code traceable 316 stainless steel for bodies, ECE R110 or EC 79 approved materials for O-Rings. LET LOK series’ other materials include brass, alloy 400 nickel-copper, hastelloy C®, alloy 825, alloy 254, super duplex 2507 just to name a few.
EC 79 certified for several configurations for sizes 1/8” to 3/4” (6mm to 16mm), pressure up to 350 bar, and temperatures -40°C to +120°C.
