The SMAC Series Swivel Design
UL Temperature Range: -40ºF to +150ºF
Highest Max Allowable Working Pressure: 400 psi
Highest Hydrostatic Test Pressure: 2000 psi
Our SMAC-series swivels are used for a broad variety of applications, designed to assist in the 360° rotation of pipework for Liquefied Petroleum Gas (LP-gas), Natural Gas, Anhydrous Ammonia (NH3), and Refined Fuels. Swivels for other liquid services are also available.
The SMAC-series swivels are designed to be used on hose reels, bulk head delivery systems, and loading arms.
- High load ball bearing minimizes misalignment problems.
- No greasing ever required.
- Three-piece seal compensates for wear and pipework loading.
- Seals solely by system pressure.
- Utilizes a three-piece seal package.
- No wearing rubber seals.
- Compensates for wear.
- Intermediary seal ring rotates at ½ speed, greatly increasing the seal life.
- Options including the “SS” Stainless Steel version for maximum corrosion resistance.
Acute Focus on Quality
- Every swivel is manometer pressure tested with CO2 vapor to exceed maximum design and safety standards.

Swivels For Smaller Applications
3/4”, 1”, 1 1/4” SMAC-Swivels
Smaller swivels are offered as the SMAC-3490, SMAC-190, and SMAC-114 which are available in 90° and straight through configurations. Since this swivel is smaller, but must endure the same radial stress when eccentricity (misalignment) occurs, two high-load rated ball bearings are used for maximum performance.
The same type of seal package as used in the larger SMAC-112 and SMAC-200 swivels is incorporated into our smaller pipe size swivels. Available in ¾”, 1”, 1 ¼” and combination thread sizes.
