Handy 4-piece pump fitting set is used to add various common bayonet fittings to SUP-style hand pumps. High-pressure hand pumps, such as those often used for inflatable SUP boards, often include a single hose-mounted Halkey-Roberts-style fitting and will not support other common valves. This 4pc set includes a ‘multi-fitting’, which locks into the hose-mounted HR adaptor and serves as a base for bayonet pump fittings. Included are: Multi-fitting, Boston, Small Boston (Stem), and Halkey-Roberts adaptors on a sturdy lanyard. Fits Aquaglide pumps: Tornado 2.5, Hurricane 3.6, Kayak Hand 10, SUP Hand 29, and Aquapark 7.3.
