MTA-BRLK-SSLK-RA-RB-Ferrules

Supported Applications

The Omega MTA, BRLK, SSLK, RA, and RB series provides replacement components for OMEGALOK® adaptors, fittings, and bushings used with protection tubes and probes. The product line includes standard dimension adaptors, reducing bushings, compression fittings, metric thread adaptors, and replacement ferrules designed to convert imperial and metric threads or connect tubing of varying outer diameters.

Operating Conditions & Performance

The series supports wetted materials in brass, stainless steel (316 SS), carbon steel, and PTFE. Specific material availability depends on the component type; for example, certain reducing bushings are available only in carbon steel. The product overview notes that PTFE ferrules can only be used with stainless steel compression fittings.

Configuration Options

The series encompasses a broad range of configurations including adaptors, bushings, and compression fittings for both imperial (NPT) and metric protection tubes. Key capabilities include:

• Adaptors and Reducing Bushings: Available in brass and stainless steel with NPT male/female thread combinations ranging from 1/8 to 1-1/2 inches.
• OMEGALOK® Compression Fittings: Offered for protection tube outer diameters (OD) from 1/16 inch to 1/2 inch with NPT male threads. Models are available in brass and 316 stainless steel.
• Metric Thread Adaptors: Convert between Female NPT and Male BSPT or BSP Parallel threads, supporting sizes from 1/8 to 1 inch (NPT) and corresponding metric thread standards including ISO 228/1 and BS 2779. Materials include brass and stainless steel.
• Metric OMEGALOK® Compression Fittings: Designed for protection tube ODs of 3.0 mm, 4.5 mm, 6.0 mm, and 8.0 mm with NPT, BSPT (taper), or BSPP (parallel) thread options.
• Replacement Ferrules: Sold in packages of 10 for tube ODs from 1/16 to 1/2 inch. Materials include brass (B-FER), stainless steel (SS-FER), and PTFE (T-FER).

Key Product Differences

Differences within the series are defined by material composition, thread standards, and dimensional specifications:

• Material Options: Components are offered in brass, 316 stainless steel, carbon steel (specific to certain reducing bushings), or PTFE. Carbon steel is indicated for specific larger reducing bushing models.
• Thread Standards: The series supports NPT threads for imperial applications and BSPT/BSPP threads for metric conversions. Metric thread adaptors are available in brass (MTA1, MTA2) or stainless steel (MTA3, MTA4).
• Ferrule Types: Replacement ferrules vary by material: Brass models (B-FER), Stainless Steel models (SS-FER), and PTFE models (T-FER). The source notes that PTFE ferrules are restricted to use with stainless steel compression fittings.
