Holmbury’s IAP Series push-pull, connect under pressure female couplings are designed primarily for the agricultural industry. They can be either panel or manifold mounted to the rear of farm machinery and enable quick changeover of attachments. This minimises downtime for farmers and machine operators. The push-pull design allows for automatic uncoupling in the event of accidental disconnection of attachment from the machine, protecting the hoses and other hydraulic components. The IAP Series is trivalent plated carbon steel and is available in either short or long nose design. It can be used in conjunction with standard 1/2″ ISO A male couplings. Dust Caps are also available.

Operator safety and failing hydraulic systems have led to a new decompression block coupler from Holmbury, the HDB, which is designed for the quick change of hydraulic attachments for skid steer, compact and backhoe loaders—as well as compact utility vehicles. The decompression feature allows the operator to alleviate trapped pressure allowing for quick and easy connection of various attachments.
Holmbury will launch the coupler at ICUEE in Louisville next month. It is rated for maximum operating pressures of 350 bar and temperatures ranging from –25° to 100° C. It offers flow rates of 86 lpm at 2 bar ∆P and decompression force of 130 Nm at 275 bar trapped pressure.
Traditional construction equipment attachment change-out is usually done through a standard set of flat face couplers that connect to the auxiliary hydraulics. Relieving trapped pressure on the attachment (auxiliary side) was achieved by using a connect-under-pressure coupler, such as the company’s HCP series. However, explained Matt Mulder, Holmbury president, “The challenge is how to alleviate trapped pressure on the machine side. The problem is that every skid steer loader manufacturer has a different set of steps to relieve trapped pressure on the machine side. Unless this can be achieved, it is near impossible to connect an attachment because hydraulic oil does not compress.”
Holmbury developed the HDB when a major skid steer manufacturer was searching for a way to resolve a problem with its high-flow grapple attachment application. Mulder said the skid steer was using a competitor’s block coupler (4BD4FH series), which decompresses by pushing on the coupling. Due to the high-flow requirement, the rigidity of the hydraulic hose and the action of the grapple attachment, that block coupler decompression circuit was opening inadvertently, causing the hydraulic system to fail and ultimately creating an operator safety issue.
With the new HDB, the decompression valve cannot be inadvertently actuated during system operation. And it only takes only a few seconds to make the change, whereas the traditional way to decompress a skid steer loader system can take several minutes or longer due to the various steps required to relieve trapped pressure within the machine side.
Mulder said that the mounting pattern is a direct interchange with Faster’s 4BD4FH and Stucchi’s Saturn block coupler series, which is installed on the end of the boom arm on the skid steer loader. He added that Faster is the leader in the market, and until recently, was the only hydraulic quick coupling manufacturer to offer a connect-under-pressure block coupler. The decompression function of the Holmbury HDB is different in that there is an external valve stem (push or pull) that when actuated, opens the machine hydraulic circuit back to tank. This immediately takes trapped system pressure to 0 psi.
The Holmbury Decompression Block coupler features HQ series couplings with zinc nickel plating. It is fitted with Nitrile and PTFE seals. A pull activation feature prevents accidental system decompression.
All couplers are flat face and are designed to the 16028 Standard. Their low profile coupling design minimizes failures due to side-loading issues. They can be ordered in coupler arrangements of ½ in. for standard flow or ¾ in. for high flow applications. The case drain coupler is a standard 3⁄8 in.
Finally, because the couplers allow for easy in-field replacement, they offer easy access for servicing of internal components and low cost.
The HDB Series is a block coupling designed for the quick change of hydraulic attachments for Skid Steer Loaders, Compact Loaders, Backhoe Loaders and Compact Utility Vehicles. The decompression feature allows the operator to alleviate trapped pressure allowing the quick and easy connection of various attachments. The HDB Series is interchangeable with the Faster 4BD4FH and the Stucchi Saturn block.
The HDB Series will be officially launched at ICUEE 2015 (September 29th- October 1st) in Louisville KY. Holmbury’s booth number is 2217.

Holmbury recently exhibited at NAHAD 2015 in Miami, FL. The exhibition was a great chance for Holmbury to showcase some of its latest product developments. Thank you to those that came and visited the stand. Holmbury looks forward to welcoming your business in the future.
Holmbury Zinc Nickel plated couplings complete 1200 hour salt spray test without any signs of fatigue or red rust. Holmbury recently submitted a selection of their zinc nickel plated couplings for testing alongside several competitor solutions.
The results were quite remarkable and proved beyond doubt that Holmbury off ers the most effective corrosion protection currently on the market. Zinc nickel plating is available as standard on several of our product series and available as an option on many others. Please enquire for more details.
A total of eight couplings, which included Holmbury zinc nickel and trivalent plated couplings, were submitted initially for 480 hours of salt spray exposure according to ASTM B117. All samples were exposed according to the instructions provided in ASTM B117, “Standard Procedure for Operating Salt Spray (Fog) Apparatus”.
As the test reached its conclusion it became clear that the Holmbury zinc nickel plating would far exceed the 480 hour mark. The test was then continued in order to ascertain the failure point for the zinc nickel plated couplings.
Holmbury Inc. has recently released it’s brand new Product Overview marketing literature. The Product Overview showcases Holmbury’s new products including the DTP, H90, IAP and LC couplings, as well as detailing our full range of couplings and valves.
