Rectus
Precision Quick Coupling & Connection Systems
Parker Rectus is a specialist in high-performance quick-connect and quick-disconnect coupling systems engineered for the safe, efficient and reliable transfer of compressed air, gases and liquids.
With an extensive portfolio ranging from miniature couplings and industrial compressed-air connectors to safety, self-venting and dry-break coupling technologies, Rectus provides connection solutions for demanding industrial and specialized applications.
As part of Parker Hannifin, Rectus combines specialized quick-coupling expertise with Parker's extensive capabilities in Fluid Connectors, Pneumatics, Hose, Fluid Control and Motion Technologies.
At MONILEK Oilfield, Parker Rectus strengthens our ability to provide complete fluid-connection solutions—from the main distribution system and hose assembly through to the final quick-disconnect point at the equipment.
Industrial Interchange Couplings
Parker Industrial Interchange Nipples are compatible for use with 20 Series, 30 Series, Rectus 21, 23, 30 Series, Universal or E-z-mate couplers. The standard male tip of the pneumatic industry, these nipples are interchangeable with similar nipples manufactured to the same requirements.
20 Series Couplers
20 Series Pneumatic Couplers mate with Industrial Interchange nipples, the standard male tip of the pneumatic industry. Available options include Sleeve-Lok, stainless steel locking balls and springs, and grip-ring sleeve.
30 Series Couplers
30 Series Pneumatic Couplers mate with Industrial Interchange nipples, the standard male tip of the pneumatic industry. The couplers have brass bodies. Standard seal is Nitrile.
Rectus 21, 23, 30 Series Couplers
Rectus 21, 23, 30 Series Pneumatic Quick Couplers connect with Industrial Interchange nipples, the standard male tip of the pneumatic industry. The 1/8” and 1/4” couplers have nickel plated brass construction, a corrosion resistant valve, stainless steel locking balls and a stainless steel valve spring. The 3/8” couplers have nickel plated steel construction, a corrosion resistant valve, stainless steel locking pins and a stainless steel valve spring
10 Series Couplers Tru-Flate Design
Parker’s 10 Series Pneumatic Couplers are the original Tru-Flate design, commonly referred to as the automotive interchange. 1/4” body size has a brass body, while standard 3/8” and 1/2” body sizes have all steel construction. Sleeve options include Sleeve-Lok and Grip-Ring sleeve.
50 Series Couplers ARO 210 Interchange
50 Series Pneumatic Couplers are interchangeable with ARO’s 210 series. Couplers have brass bodies. Nipples are constructed of steel. Sleeve-Lok is an optional feature.
Universal Coupler
UC Series Pneumatic Quick Couplers connect with Industrial Interchange, 10 series (Tru-Flate), and 50 series (ARO 210) style nipples. While the best performance is obtained by matching like series couplers and nipples, the Universal Coupler permits multiple series nipples to mate with one coupler.
70 Series Couplers Lincoln (Long) Interchange
70 Series Pneumatic Couplers are interchangeable with Lincoln’s “Long Stem” series couplings. Couplers have brass bodies and steel valves. Nipples are constructed of steel. Sleeve-Lok is an optional feature.
Rectus 25 Series Couplers High Flow European Interface Formerly RF Series
Rectus 25 Series Pneumatic Couplers are designed to increase flow and reduce pressure drop through the coupling. Rectus 25 nipples have up to 2-1/2 times larger flow area than standard industrial interchange nipples. The increased flow results in greater tool efficiency and decreased air costs. Couplers are nickel plated brass and nipples are steel.
TL Series Couplers Schrader Twist-Lock Interchange
TL Series Pneumatic Couplers are interchangeable with Schrader Twist-Lock style couplings. Couplers have brass bodies and steel sleeves. Nipples are constructed of steel.
IH Series Snap-tite Design
IH couplers are steel with a cylindrical valve designed specifically for pneumatic use. When paired with an unvalved/plain H Series nipple, it functions as a durable single shut-off connection. Standard seal is nitrile.
Tool-Mate Series Couplers (Standard) Rectus 25 and Industrial Interchange Styles
Tool-Mate Series are light weight and easy to operate with a non-marring body. Couplers are constructed of Polyamide material with galvanized steel port ends. Springs, balls and pins are stainless steel and locking fingers are polyacetate. Grey body color designates standard, non-venting style coupler.
Tool-Mate Series Couplers (Exhaust) Rectus 25 and Industrial Interchange Styles
Tool-Mate Series are light weight and easy to operate with a non-marring body. Exhaust style couplers allow disconnection at zero pressure to avoid dangerous hose whip. Couplers are constructed of Polyamide material with galvanized steel port ends. Springs, balls and pins are stainless steel and locking fingers are polyacetate. Black body color designates venting, exhaust style coupler.
E-z-mate Series Couplers (Exhaust) Accepts Industrial
E-z-mate Series are exhaust type quick couplers that are designed to safely relieve air pressure prior to disconnection. When the valve sleeve is twisted to shut off air flow, it automatically vents downstream allowing for disconnection at zero pressure and eliminating the risk of “hose whip”.
GF Series Natural & Propane Gas
GF/GF-1 Series couplings are valved on the coupler half and will automatically shut off gas flow when coupling is disconnected and automatically open on connection. They also incorporate a safety fuse in the nipple that will shut off the gas supply to your application in the event temperatures exceed 350°F.
