Yor-Lok Fittings for Stainless Steel Tubing
(SAE Straight) Male
Threads with Gasket
A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
316 stainless steel fittings have excellent corrosion resistance.
BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

- Specifications Met: ISO 8434, SAE J514, except fittings with BSPP and BSPT threads meet SAE J514 only
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They withstand high pressure, so they’re often used in hydraulic applications. Made from 316 stainless steel, they resist corrosion from water and chemicals. A complete fitting requires a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
BSPP threads and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Crimp-On Hose Fittings for Hydraulic Fluid
Crimp these fittings onto hydraulic hose for a permanent, leak-tight connection. Since they crimp on, they handle higher pressure than screw-on fittings. To install, use Parker crimping tools and dies (not included).
Fittings with a female end swivel 360° until tightened without you needing to move or twist the entire hose, making them easy to install.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.

Straight-Flow Rectangular Manifolds
Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows fluid or air to follow a straight path, improving flow through your system. It also frees up the ends of the manifold, so you can mount it in corners and in narrow spaces. Manifolds are also known as headers. They have mounting holes, so you can mount from the top or side.
Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.
Use a plug (sold separately) to close off any unused inlets and outlets.

Low-Profile Square Manifolds
With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air, water, or hydraulic fluid to three locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.
